I ordinarily hate partisan "why the Bible doesn't hate gay people" material because it is either weak on scholarship, balance, or common sense, and these far too often tie up their conclusions with a big bow of defensiveness, or worse, ambivolence to the Bible.
But I found a resource of the "Gay Bible 101" genre that I like, online and free to boot. It is within one of those sites you're not suppose to admit reading because of its occasional not-for-kids content. (More tacky than tawdry.)
Adults, take note of the well-entitled One More Article Explaining That the Bible Does Not Condemn Homosexuality at Adult Christianity.
