“Simply standing up for decency would solve a lot of problems. ”

That is where you are letting them get the better of you. Leftists no longer care for human decency. It does not sway them. You can’t appeal to the decency of a leftist any more than you can appeal to the decency of a 7-year-old who really wants what you have.

Counter-attack, however, works. Leftists are so unaccustomed to counter-attacks that they are ill-equipped to fight it.

Try it, and see. They will flee with the cowardice of a rabbit.
