There is a way to look at christianity and the bible without being anti-gay.
1) As for Leviticus, I like to ask fundamentalist xtains when they decided to start keeping kosher? I thought Paul said keeping to the old Judaic Law didn't matter. It matters a great deal to orthodox Jews of course, and I respect that, but it doesn't apply to what makes a good christian.
2) Paul's letter to the Corintians 6:9-10. There is some debate about what he is referring to. I'm sure the subtext was clear to the Corinthians, but it has been lost to us. For an interesting alternative view, go here. He seems to be talking about courtesans who spend more money on clothing and such than helping their communities.

I certainly do accept and welcome gays into my life. I don't see them as "possessed" or "evil" or "wrong". People are born gay just as I am born straight. It's built into the system.
Besides that Jesus person was pretty big on "loving your neighbor as yourself." That "hate the sin, love the sinner" mantra is crap. You either love someone in the some totality of who they are or you do not. If you don't, then don't label it "christian," because it certainly isn't.
