Standard operating procedure for left wing activists according to Saul Alinsky's Rules for Radicals:

13. “Pick the target, freeze it, personalize it, and polarize it.” Cut off the support network and isolate the target from sympathy. Go after people and not institutions; people hurt faster than institutions.

6. “A good tactic is one your people enjoy.” They’ll keep doing it without urging and come back to do more. They’re doing their thing, and will even suggest better ones.

Liberal activists, particularly LGBT activists, are the worst political threat to a free society since communism, and it makes sense that they would be, since they are the progeny of communists.
