I don't know much about Warren Jeffs but the similarities between some of his beliefs and Islam are apparent.
He's being accused on being an accomplice to rape for arranging marriages between young girls and older men. I have one word to say on that "Ayesha". See too, Zarqawi's child bride.
He warned a teenage girl forced into a "spiritual marriage" to submit to sex with her husband. Has he been reading the Koran? "Your women are a tilth for you (to cultivate) so go to your tilth as ye will."
Now I don't for a moment condone Jeff's actions but it seems odd that his particular brand of multiple marriage and marriages between young girls and older men should be targeted but the practice by Muslims is accepted as some sort of cultural norm. And while I can't see the ACLU rushing forward to defend Jeffs (he's probably too "Christian" for them) they do seem to be oddly in favour both of multiple marriage and sex with minors- check out Clayton Cramer's blog for more on that.
