Oh I agree not everyone is that way over there, but I've also noticed some of the nastiest and hateful things I have read there are never even called out by the posters that "aren't that way". So I'm not sure what that says.
Have you, in person, real life, tried to change someone's opinion that is racist? Were you successful in changing that person's opinion and outlook? If yes, then what church do you preach at?
There has been plenty of times these people were called out, and it doesn't do a damn thing to change their opinion.
