A big share of black males are Trump supporters, going by older surveys I’ve seen. Could be reflecting that.

There’s got to be some complexity behind that (and there are articles on it), but one theory I’ve heard is that many feel “abandoned” by the establishment like, say, young males (who also skew more Trumpy than 30+). Maybe social media usage is a factor too? Keep in mind the public knows Trump as the anti establishment candidate.

I know this is just one person. But when I lived in the US my daughter had a black nanny who was a new-born Christian. One time she tried to explain me how in the Bible it says Arabs are evil or something. She didn’t use the term “evil” but her explanation alluded to it. Searching “Arabs bible evil” brings up a lot of articles and verses about the matter, so it isn’t just Black churches that promote this worldview.

I think it's evangelical Christianity. Persia (Iran) is often maligned in the Bible and the apocalyptic Book of Daniel refers to the "Prince of Persia" as a spiritual opponent, and some have identified this figure with Satan himself. The struggle between Christianity and Islam is also framed in apocalyptic terms by many radical pastors, and Iran is a powerhouse of Islamism. The Black community also has a lot more interaction with "Islam" than most white people in America due to popular, black-centric, Islam-themed religions (Nation of Islam, 5 Percent Nation, etc.) that cropped up throughout the 1900s as an alternative to the "white man's religion" of Christianity. This interaction may lead to higher degrees of fear of an upcoming "Islamic invasion" that has been fearmongered to death by pastors all around the country since 9/11.
