Bigotry is ignorance ... brazenly speaking out against an entire group of people is extremely negative karma.
Now ... I know that Rick Warren tries to blend a very moderate and compassionate tone with his condemnation of homosexual acts ... he still stirs the fires ... he's still a symbol of that movement so I can't just keep quiet.
I know the dogmatic religious zealots are unswayed by common sense. They will believe their book tells them to hate, and to do so righteously.
: Does no one trust the words of Christ, anymore? You can't quote Christ himself for anything definite when it comes to gays. Promiscuous people? Yes. Loving couples? No. The notion on that is ever vague. Like much of the Bible is.
In the Buddhist perspective ... homosexuality is such mundane activity ... and it, in addition to a host of things that MANY people are susceptible to, are to be regarded as distracting and worldly. Both Christianity and Buddhism teach forgiveness, compassion, and detachment from the world.
In that perspective, my passions, personally, are quite cool.
Like, the old testament 'eye-for-an-eye' still finds favor amongst several protestant denominations, even though it was supposedly superceded by the greater teaching of Christ to "turn the other cheek."
Because revenge is also negative and worldly.
Speaking harshly of others and judging them is negative and worldly.
Om Mani Padme Hum.
... on an aside : piercing scholarship of ancient texts reveals their context, and what it meant for societies of old for these things to transpire.
On that note, I'll leave you with a highly enlightened verse from the bible:
"Above all, love each other deeply, because love covers over a multitude of sins."
1 Peter 4:8
