I presumed by that statement, you said the perverts offered nothing, meaning they did not offer their vote. Apparently though, you do accept their votes, and obviously if they vote for conservatives they have something to offer.
If McCain is simply asking them for their vote, and you agree that you are not rejecting their vote, then I think you are incorrect when you say that you think they have nothing to offer.
Yeah, like when they (the Log Cabin Republicans) refused to endorse President G W Bush in September 2004 -- two months before that election? They did so specifically because Bush supported the marriage amendment. You know, "one man, one woman."
Keep telling yourself the LCRs are conservatives, and while you're at it call yourself one, too, for supporting their agenda.
