"Most politically active homosexuals seek to denounce what they perceive to be bigotry,..."
And therein lies the root of the problem. They denounce PERCEIVED bigotry through actual bigotry. Not some "soft bigotry" like holding a private opinion, but hardcore, full-on, would-be-illegal-the-other-way-around bigotry. They advocate firing people who dare express a contrary opinion (Frank Turek). They advocate forcing religious organizations to either violate their principles or close (Catholic Charities Adoptions). They advocate witholding business licenses from legitimate companies because of their political views. All in the name of "tolerance" and "inclusion."
