How does religion justify racism?

[Jason]

How does it do so and how much does it? Why does it do that? What are solutions?

[Stoic]

So, by greek definition, racism is when one race think of other race inferior to them without probable cause. In modern day, people call you racist for pointing out patterns all across the world. If something is true, it is not racism, it is a fact. If somebody asks me: Do you feel safer in a group of 5 black people or 5 white people, of course i would say 5 white people and that is not racist. I've seen how violent black people are towards white people today.

Can you give an example in which religion justifed racism?
