Calling someone a communist or socialist is the latest duckspeak from minitrue. It’s intended to suppress all thought. It’s also intended to be impossible to refute. It’s like if you were trying to muscle in on a cave dive rescue of some kids and suggested the rescuers use your submarine, and then they tell you your submarine is useless, so you insinuate that they are pedophiles. It’s a meaningless tar-baby statement meant to distract from meaningful discussion.
