There is no explicit depiction of sexual activity in the Bible. Ezekiel 23:20 is probably the most lewd verse in the entire Bible, and it is roundly condemned as sinful and inappropriate in the following verses.
I would have no problem with making those age restricted, if that's what you mean (after the all, the city is only banning the distribution of these materials to minors). We already do that with violent movies, after all.
But the Bible explicitly condemns most of these things (except the God-ordained genocide in the Pentateuch I guess). It's a bit of an oversimplification to compare that to books that explicitly condone and encourage sexually deviant behavior.
Sounds like you have no problem with using racist language, as long as it isn't directed towards you. Hypocritical much?
