I know this subject came up about some of the ridiculous stuff that is in the Bible, Koran, etc.
If you've got some time, this is a good read on the Old Testament:

Leviticus is a funny book for modern Christians. Along with Deuteronomy and swathes of Exodus and Numbers, it lays out the Law for the Israelites. But it’s largely ignored by modern Christians because it’s felt that Jesus replaced the Law (except where He didn’t) and that Paul said a lot of it didn’t apply (except for the parts that did). And for all of that, many are still willing to cite Leviticus for things that they think are sinful, while ignoring it for things they don’t.
In other words, people tend to cherry-pick which of the Levitican laws (or, for that matter, all of the Old Covenant, not to mention most of the Bible) they think still apply, and which don’t.
