You didn't mention the odds of a woman getting HIV from a woman, which I believe are far lower still.
I mentioned it. I said it's very unlikely for a man to get AIDS from a woman, but that doesn't stop the woman from getting it from a man.
But my point was just that AIDS isn't some form of 'punishment' for gays. Because if that's the case, God punishes the innocent with the guilty and allows much greater evil than sexual sin to exist and continue unabated.
