It all goes back to this: liberals say that they believe that everyone has the right to live as they wish, but not when it comes to those who are not yet ready to out themselves, especially if they are republicans. Gay republicans are in jeopardy of being outted if they do not believe in the gay marriage agenda - and there are many.
Many gays do not support the whole "gay marriage" agenda - check out Tammy Bruce, for an example

Liberals want to give people privacy, all right. Until it cuts across their own agenda....
