Yup. Much of the difficulty IMO is that the texts of all of the mono-theistic religions of Abraham have plenty of words that endorse all sorts of genocide and slavery, and indeed many words that implore followers to pursue such ideals with zeal. Now that those mono-theistic religions of Abraham happen to be followed by many or most of the people from most of the richest countries in the world, and those countries have constitutions forbidding much of what those ancient text endorse, one is left with the conundrum of fitting a faith that says enslave into a country that forbids it ... and the only solution is to codify "legitimate" as those branches of the faith that have abandoned those segments of text and faith that have been constitutionally forbidden (e.g. slavery).
The texts of the religions of Abraham are intensely militaristic (devoted primarily to human conflict and domination, how to go about human conflict and domination, how to dominate, how to be dominated, who to kill, when to kill them, and how to kill them) and with all of these faiths there are followers who continue to adhere to those principles. There are some bits about other things, food, hygiene, and a good chunk of stuff about sex ... but a lot of war.
