So the bigots are not only on the Republican side like you claim, but also on the Democrat side? You seem to be kind of disproving your own point if you are admitting that Democrats won't vote pro-gay either. We won't have 60 senators who will vote for gay rights when 59 of them are Democrats?
There are conservative Democrats who are not friendly to gay issues and the "gay agenda". I never said there wasn't, or that there were no "bigoted" Democrats. The fact remains that of the two major political parties only one is even remotely close to being a friend of the GLBT community and its issues.. and that's the Democratic party.
Your entire post is filled with non-sequiturs. Democrats
do vote "pro-gay". More Democrats than Republicans vote "pro-gay", but nowhere would anyone reasonably claim that a Democratic super-majority would necessarily advance, significantly, the "gay agenda".
What do you suppose a Republican super-majority would do for the "gay agenda"? Well, the conservative base would probably try to pass all sorts of things that would solidify the position of GLBT individuals as marriage-less, adoption-less second-class citizens. They might even try to pass a federal Constitutional amendment defining marriage as one man, one woman. Where would these attempts go? Well, they would be unlikely to pass because Republicans, in order to attain a super-majority, had to field more liberal or moderate candidates to win over areas traditionally held by Democrats.
So, while a Democratic super-majority won't get far advancing gay rights, a Republican super-majority won't get far pushing back gay rights. It's a rub, but it is also quite clear.. for advocates of gay rights such as myself.. which is the more desirable of the two: trying to advance is better than trying to push back.
At the end of the day, on almost every issue or agenda, super-majorities in Congress are a guarantee of failure.. and nothing more. The enlarged intra-party diversity of a super-majority abhors the unity required to pass sea-change reforms.
