Bottom line: homo's exploit other homo's to hurt Republicans?
I started to answer your question, and found things getting more and more complicated. The fact is, bottom line, the gay political position is unnatural and delusional. It requires you to draw all sorts of lines between what's politically correct and what isn't, and in a case like this they endanger themselves by revealing the contradictions inherent in their beliefs.
The same thing threatened to happen with the left wing media attack on pedophile priests. They tried to draw a sharp line between pedophile priests (horrible) and gays (wonderful), but the lines in fact blur. The great majority of the priests in question were not, in fact, pederasts but ephebophiles, or lovers of young men. They were, in fact, almost all homosexuals.
So, what started out as an anti-Catholic campaign turned into a campaign to weed homosexuals out of the priesthood. Naturally they didn't intend anything like that.
