No one said it was confined to just one group but sometimes it is. You can't give me the Nazis and the Jews "were good people on both sides." Yes, hate dominated the Klan.
But given I've had pieces on the page about how Castro promoted hate and intolerance I'm unsure why you thought at point. So I am not mistaken.
I do know evangelicals up front and personal having been one, gone to their Bible college and followed them closely. High numbers of them think all Catholics, Jews, and Mormons are going to hell and deserve. They are more intolerant of blacks and whites marrying, more intolerant of gay people, utterly ballistic that trans people exist, are more likely to despise immigration. Polls show that including polls from evangelical groups such as Barna.
