Plenty of people take them literally. I see people justifying the denial of equal rights to people based on the book of Leviticus every single day. So you're not against gay marriage then? It is only condemned in the Old Testament after all...
You know, I rarely find Jews that adhere to Leviticus to the letter. Not that I'm out interviewing them or anything, to know for sure. But, aside from the food (eating kosher), do they even adhere to the clothing rules anymore? It's somewhat rhetorical. That's what's so potentially-volatile about religion; you never know who is going to take some passage in a literal context and go off.
