I'm sure that is true... but no one sector of the world has a monopoly on that one.Except it's not unusual for religion to teach people who to hate. Like homosexuals, with legions of Christians and Muslims offering scriptural support for their disdain of homosexuals. Or the many LGBT teens who learn to hate themselves because of what scripture says. The same scriptures that have also been used to repress women. Murder people believed to be witches. Hate for apostates is something that doesn't happen unless the religion teaches it.
One can be just as dogmatic in hating religious people as visa-versa.
