Answer:
This is based on my experience with a conversation with someone over the internet. That guy I was talking to was a racist, i was unaware of it until there was a topic about a white girl married to a black guy. I was intrigued so I asked him, "Why do you hate them?" then he answered something about his religion.
in his religion it was believed that someone with different race as them is a threat for their future and a treason to their God. Because their God wanted to keep their race pure, unmixed with other races. Because it was believed that the mixing of race is considered as a "genetic pollution".
Explanation:
That's what he said, religion is one of the factors why.
