look up America and our Christian heritage and tolerance for all religions and beliefs.
Christ teaches love and equality as atheist teaches what ever it learns from the people they are around. the morals and civility of the land every thing atheist have learned about morals they got it from Christians and other religions or the law of the land they live in. if killing people for disagreeing with you about religion became legal in America would people with no morals or civilly do it? of course they would sooner or later because of hatred against those people. jesus teaches to love and not hate.if you truly follow Jesus teachings you would not commit such a thing unless in self defense or war.
