All organisms have defensive mechanism.
Organisms can only survive by assessing threat and acting upon them. As humans are organisms, they are no different. In order for race-culture to survive on a territory, it must defend and preserve itself from outsiders and invaders. While it's true that every nation has history of invasions and incursions, they only became stable civilizations when there was sufficient political, military, and legal power to protect the nation from further invasions. Without such security and stability, national order isn't possible. This is why stuff like 'UK is a nation of immigrants' is retarded. UK was constantly invaded BEFORE it was a nation. The invaders came at will on warships and laid waste to native populations. (Also, the invaders of the past were fellow white Europeans, so they could eventually meld with the existing populations.) Once Britain gained security, order, and power, it defended itself from further foreign invasions. If foreigners did arrive(and settle), it was with the permission of the state in consideration of national interest.
A nation that cannot stop or control the inflow of outsiders is the victim of military imperialism, demographic imperialism, and/or financial-ideological imperialism(that colonizes native souls with the mental virus that 'diversity' is good when it spells doom for native identity and culture).
Look at nature. All animals must sense and assess degrees of threat level. When humans encroach on wolf territory, the wolves growl. Hippos don't like Negroes coming closer with spears. Bears fight other bears to maintain territory for food, mating, and security. Birds guard their nest and attack threatening species. Without such defensive mechanisms, no complex organism could survive. Bees don't just allow any bunch of organisms to come and eat the honey. Bees work like crazy to collect the honey to feed their own community. (Some say modern societies cannot produce enough life and that's why they need immigration to get new workers. But if modern societies have given up on life, it means they are soul-sick and culturally misguided, and THAT DISEASE should be diagnosed and treated. If someone won't eat, don't give his food to another person. Convince him to eat again.)
Globalism has infected Western minds with the notion that their natural defensive mechanism is 'evil', 'racist', and 'xenophobic'. It dilutes hormonal instincts and weakens carnivorous instincts, turning whites into human herbivores. Brits have been turned from lions(without a powerful pride of territory) to rabbits(who just wander around aimlessly in their own nation without claiming it).
Globalism is like quasi-spiritual cult of rapture. It’s the Promise of Deliverance, a hopeful ecstasy of departing from the ‘sinful’ nationalist flesh and becoming one with the transcendent globalist spirit. It's secular cult of being 'saved'.
Since all histories are associated with cultures/nations and since all cultures/nations are stained ‘sinful’ deeds, globalism offers deliverance from 'tribal' sins via collective union o all peoples in Glob Heaven. This rapture is experienced through PC kumbayah and Pop Culture orgiastics. Take leave of roots, senses, and obligations. Just scream, feel orgasmic, and let one’s soul lift from national earth to globo-heaven.
So, even though UK is being remade by massive invasion, Brits have no defensive mechanism left. If Brits still have any aggressive drives left, it is against their own will for self-preservation. (Jewish ideological control infected British minds with the sanctimonious notion that white Britons must serve the interests of the holy Jewish minority before their own. This elevation of minority-as-sacred-group led to white Britons placing every non-white minority above whites on the national pedestal. In time, white Britons even came to worship homos. That this is a globalist-imperialist phenomenon is made clear by what is happening in Ireland. Even though the Irish have defined their own narrative against Great Britain, its current national agenda is identical to that of the British because both nations are under globalist Sorosian control. Both nations worship non-white minorities and homos above native whites and real-sexuals who are to be attacked and denounced if they resist massive immigration-invasion and homomania. This is why Ireland has a Hindu-Homo prime minister and why London has a Pakistani-Muslim mayor. The two peoples who never agreed on much are now totally agreed on national self-destruction and white self-loathing as the highest virtue. Other than the ideological infection of Jewish-controlled globalism, there is the factor of Afromania and Jungle Fever that have whites all over the world worshiping Negroes as MLK-Mandela Magic Negro race and 'cool-badass' race whom whites must admire, praise, and emulate 24/7.)
It used to be Brits were most aggressive against would-be invaders, such as Spanish or Germans. Now, they are most aggressive against would-be-patriots-and-defenders. Brits get most passionate about attacking and destroying patriots and offering UK to the Sorosian god of globalism. UK is no longer seen as a nation among nations but a part of a globo-rapture-empire of Jew-worship, homomania, Afromania, and Diversity. UK must serve that higher god by surrendering national identity, borders, and sovereignty. UK is now to the world what Puerto Rico is to the US.
And the elites of UK, instead of standing up for national defense and preservation, lead the nation in surrendering to globalism and mammon. Also, elites have used the media and academia to infect the younger generation with the idea that UK has always been a 'nation of immigrants', a defenseless domain that welcomes invasions than fends them off.
What UK really needs is AUSTERITY AGAINST DIVERSITY, 'diversity' being just euphemism for invasion.
Now, some organisms are compatible. Even in the wild, lions coexist with gophers, turtles, vultures, and etc. The biggest threat to lions are other lions.
Likewise, people of any nation can co-exist with birds, squirrels, pond turtles, seagulls, chipmunks, rabbits, raccoon, opossums, and etc. People need to fear other peoples the most, just like lions need to fear other prides of lions the most. White Australians have nothing to fear from kangaroos, koala bears, or wombats. Not even from crocodiles as long as one doesn't get too near them and prod them with sticks. They have far more to fear from massive immigration of Asians, Arabs, and Africans.
Different groups of humans have competing identities, interests, narratives, and appetites.
Palestinians weren't done in by pigeons, fish, or jackals. They were done in by other humans: the British imperialists, Zionists, Soviets, and Americans.
Tibetans and Uighurs are not being done in by sheep, eagles, toads, or snakes. They are being done in by other humans, the Han Chinese. The biggest threat to any organism is, more often than not, others of its own kind. Because they have similar objectives, they compete and fight for the same thing. It's like a man who wants a certain woman need not compete with male pigs, wolves, moose, hippos, wombats, and etc for her. Those other species are not interested in the woman. He must compete with other men. A horse, bison, bear, hamster, python, or cougar will not take a white woman from a white man. It is the Negro who will.
Nation is the same way. To own it, a people must compete with other peoples. Lose the defensive mechanism(under whatever fancy pants 'progressive' idealism), and it's only a matter of time before you lose your nation, narrative, and culture.
