There's long been a violent Clash of Cultures between the Muslim World(especially Arab) and the Afro-pagan World. Arab Muslims considered black Africans to be wild, savage, lascivious, and beastly. So, Arab Muslims not only enslaved black Africans but castrated them to tame their Jungle Nature. It was Jihad Justice against Jungle Junk. This went on over many centuries. Scholars say Arabs enslaved millions of black Africans, seeing them as little more than animals.
But Arabs also spread Islam among black Africans, and many black Africans became Muslims and waged Culture War on other black Africans who were seen as mired in tribal-pagan-savagery.
As both the West and the Muslim World were dominated by spiritual institutions and communal values, the main thrust of their moral-cultural narrative was directed against black African savagery that was regarded in a negative light, not good for much of anything. White Christians and Arab Muslims held that black Africans had value only as slaves or converts to Christianity or Islam. They didn't find intrinsic value in black African-ness.
That was then, this is now. With the ebbing of religion and morality in the West, Pop Culture became the main mode of cultural expression and experience. Also, with the fading of traditional mores and authorities, the new religion became Political Correctness or Cult of Social Justice. PC came to be controlled by Jews. YMCA buildings in colleges are now more likely to host homo celebration or hip hop orgy.
This gave a huge advantage to blacks. With the rise of electro-amplified Pop Culture, black music or black-inspired music came to dominate the modern world. The most popular music among Western elites is reggae. Among ordinary people, it's Rap or Hip Hop. Also, sports as the New National Culture led to worship of blacks as local heroes since blacks are most athletic. Also, the erosion of moral values led to sexual licentiousness, and the cult of black twerking booty and hung black dong became iconic in the Western/Modern consciousness. Black savagery, once regarded as the lowest state of human existence, became the most popular and in-demand(even though this techno-savagery often appeared in the form of imitation by white, brown, Jewish, Asian, or Hindu performers).
So, if the religious-moralistic Arab Muslim World and the White Christian World once had in common their low regard of black savagery as just backward, animal-like, crazy, and beastly, those facets of blackness came to be admired, adulated, fetishized, sensationalized, and even revered in the Age of Electronic Mammon, at least in the technologically advanced West.
White girls now grow up to Rap music and Jungle Fever. White boys now grow up admiring black athletes who routinely beat up white males and colonize white wombs. Cuck-dom is the state of the Modern West, and most white men(except those in the Alt Right) have accepted their inferior racial status via-a-vis blacks. This is why we have 'whiggers'(and even 'chiggers' or yellows who appropriate blackness to compensate for their innate 'lameness'), but we don't have blacks trying to imitate country music or J-Pop.
Much of Pop Culture in the US and EU are variations of Jungle Fever where white girls imitate black girls and fantasize about having sex with blacks and having mulatto babies. And there is hardly any resistance from white males since they've been lobotomized and castrated. (White fathers are more afraid to say, "I wish my white daughter marries a white guy" than "I'd be proud to see my daughter be knocked up by a black guy." ) Indeed, even after Muslim bombings, these cucked out males condemn terrorism mainly in defense of concerts that promote Jungle Fever among white girls and cuck-wussiness among white males. For most whites, Homomania and Jungle Fever are their main cults or neo-religions.
But blacks prevail over whites not only with sports, music, and sex. Because of the Slavery Narrative(and milking of 'white guilt' by PC) and the bellowing voice of the Negro, whites also see blacks as the Magic Race, the Holy Race, the soulful people of god. Your average white American worships MLK more than God; your average European worships Mandela more than Jesus. Whites feel no comparable reverence for figures of other races. Even Gandhi has faded in appeal. Dalai Lama is more a figure of adoration than adulation.
But if White post-Christian West surrendered to Black Savagery, the Arab Muslim World is still in a state of Culture War with Black Africa. Arab Muslims never felt sorry or apologetic for their imperialism in Africa or black slave trade. If Christian morality is steeped in the cult of guilt, Islam is immersed in other matters. Muhammad preached to his followers to be warriors, hardy and ruthless. So, Arabs don't feel sorry or guilty about their historical role in Africa.
Also, if Christianity is a spent force and only survives in its secularized form of PC, Islam is still very much alive as a spiritual and moral force. As such, it continues to view black African culture as savage, backward, beastly, and demonic. If the West gave up its traditional certitudes and now worships Negroes as heroes, studs, angels, and demigods, the Arab Muslims still regard themselves as culturally, morally, and spiritually more advanced than black Africans, indeed by light years.
So, it must be strange for Arab Muslims to come to the West only to realize that black techno-savage culture is favored over Islamic values by the white natives who are into reggae, jungle fever, black sports, and Magic Negro idolatry. Hail Mandela but hell with Ayatollah and Arafat.
Even though Muslim terrorism is characterized in terms of Islam vs 'Western Values', it is really a Culture War between Arab Islamism and Black Africanism(that has culturally colonized the West and is now sexually colonizing the wombs of white women, with the sheepish approval of pathetic cucked-out white males). It is Jihad vs Jungle, a Clash of Cultures that's been going on over a thousand years. This battle is now being waged on Western Soil since both black Africans and Muslims have been allowed in huge numbers.
This aspect of the clash eludes detection under the radar because some of the Muslim attackers are black Africans and most of the victims are white Europeans. (Of course, there is also the factor of PC pushing the fanciful notion of all People of Colors being united against 'white racism'.) But devout black Muslims have made the cultural shift from Jungle Jive to Jihad Justice. They've come to reject Afro-pagan-savagery.
Also, those white victims of terrorism are often 'whiggers' to the extent that their main mode of entertainment and enjoyment involve black sports, sex, and music.
In that sense, the so-called Clash of Civilizations we see today isn't Islam vs the West but Islam(still a spiritual-moral force) vs Whiggers(whose main objects of worship are electro-amplified Afro-savagery and homomania).
