All that can be advocated here is a peaceful, and lawful, solution. And I am game for that.
Peaceful and lawful does not have to mean pleasant.
Outing them and firing their wives/husbands from their jobs would work.
Telling your kids not to play with their kids.
Kicking their kids out of private schools.
Refusing them service at restaurants.
Public shunning, mocking, etc.
There’s a lot that can be done, case-specific, situationally specific. Just needs public willingness and outcry.
