To expose the hypocrisy, if this was supposed to be a Christian forum, where did Jesus preach that kind of racism? You shall know Christians by their fruits, so you may be surprised with a "I have never known you" answer at judgment time?
If ancient humans were savages and condoned abuse in writings, why should we borrow that into the modern doctrines of a more informed society? Admitedly, some people are bigots and some are also involved in the promotion of obscurantism.
I was raised in a cult that in my place and time didn't include racist doctrines, although some members can still be racist. It did promote racism and slavery in older propaganda. The pseudohistorical "Curse of Canaan" doctrine claims that a specific ancient tribe was black and of a slave class due to divine judgement, producing a different people, naturally more subservient... It's of course bullshit. (In "The Golden Age" magazine of 24 July 1929 at p.702).
As a white male teen still in the cult, a very fine black lady was often in my circle showing interest. In eventual conversations with her father, he soon told me that in his point of view mixing colors shouldn't happen to "preserve the race", mixing somehow being a threat to that. A ridiculous argument, considering that not every couple is of mixed color, with humans having mixed for a very long time, the fact that we're all homo sapiens sapiens, etc. I long left the cult, but my current girlfriend is also black.
In the southern US, some used an altered Bible version to indoctrinate slaves. It's easy to cite verses describing ancient slavery but also easy to find one with threats against those who alter scripture... The KKK tainted the reputation of Christianity, like "Christian nationalist" white supremacist Neo-Nazis today.
