Why does the obviously large majority of American conservatives suffer under crushing tyranny of socialist politicians? Why do the most liberal democrats get elected in even very conservative states?
The answer is apathy. The voters in those states simply DO NOT CARE enough to get active, go to the polls, elect their people, etc. Hell, they don't even have "their people" to elect in most cases!
The gays are a similar situation. Most gays just want to be, they do not want to get married, they do not want to scream about gay pride and equality, they just want to live their lives with the least amount of problems as possible.
So I think your comparisons to the "silent majority" of Muslims is not correct. In fact, I think that the "silent majority" of Muslims are another apathetic group, one who may not "get it" until it's too late.
I can't accept your premise that "most gays" just want to live their lives quietly and peacefully. If that was so, the world would not be kowtowing to their insane demands. Of course, their willing handmaidens and assistants in the media - basically the entire left, being secularists, have swallowed the homosexual agenda in toto. So they have great allies.
But considering the popularity of "Gay Pride" parades, GLSEN in thousands of schools across America, AND the fact that Tammy Bruce is about the only homosexual spokesperson who decries the radical "gay" agenda, you are wrong.
In the Moslem world, we don't really know how many are radical and how many aren't, since even the non-radical ones may be afraid to speak out against the radicals for fear of their lives.
In the US, no homosexuals will be slaughtered if they speak out for moderation.
The silence is deafening from such "moderate" homosexuals is defeaning.
