You may be doing more good than you know.  The only reason I ever engage on the topic of homosexuality is that I am aware that many people read these posts who never post at all.  Some of them may be struggling with sexual and gender issues. I write for them, knowing that most of the right-wingers are hard core homophobes. (I choose the word deliberately: I think they really are afraid, if not precisely of homosexuals, then of homosexuality and/or sexuality broadly understood.) If you are able to help save some struggling young person (or older one for that matter) from internalizing the superstitious nonsense that drives so much of the religious gay bashing rhetoric, then you've done enormous good.
