@TBR: I don't know about your jurisdiction, but here, it's under disorderly conduct in public (which houses other miscellaneous laws like playing musical instruments in public without a licence and killing horses).
Diqiucun_Cunmin: You're right, it is a double standard. How would you like it if you saw two gay men kissing? Repulsed. It's not like it's actually hurting anyone though and making it illegal to do it is extremely restrictive and authoritarian. You mention the Bible in your vote, but that's personal choice and belief and should not be the law of a secular government.
