The photo at right shows the arm of a man who tattooed Leviticus 18:22, which is the only clear place in the Bible where homosexuality is unambiguously condemned (along, and with equal force, with touching the skin of a pig, seeing a naked woman menstruating, wearing more than one kind of cloth at at time, etc. etc. etc.)
If I ever get a tattoo I'm going to get one of Leviticus 19:28, which reads:
28 You shall not make any gashes in your flesh for the dead or tattoo any marks upon you: I am the LORD.
That would be pretty cool.
