People nowadays are quick to resort to insults and anathemas who have no real meaning anymore (bigots, etc.).
it's true many people who are in LGBT groups or support them, lean to the left or extreme left, and have their own conception of freedom of expression and opinion. (quick to ressort to censorship, deplatforming, etc., for whatever statements and opinions they dislike).
that said, many gay men, lesbians, etc, do not feel represented by them and have nothing else in common apart from their sexual orientation.
otherwise, one piece drags on too long and people getting bored of it + young people flee forums and go in other spaces.
