That question can still be asked, only in reverse.
There are a few homosexuals who aren't brownshirts, if that's what you mean. My 2 or 3 gay LP friends are the exception: pistol packing free-market folks and the like.
Most other gay people I know are not political, they just want to be themselves and have no desire to be radical.
The radical homosexual lobby, in my opinion, is a very small but vocal minority.
