My "smartness" is still "out" on this subject.
Let's just say that it's far easier for gays to believe there's a gay gene, than for them to do the hard work of changing their lives.
If they want to live gutless lives, rather than meet the pain head on, and break through to the other side, that's their business. But I know what's available, and I refuse to give gays a pass. There exists in reality God's grace - NOT a gay gene.
