But Maoism and other forms of Marxism are truly bad ideas. We should use the enforcement mechanisms of social norms, such as mockery, to drive them from typical discourse.

I think we should take a page from that other ideology to whose *ss Leftists’ lips are firmly affixed, Islam, and force Marxists to “convert to capitalism, pay the jizya (we could call it a “stupidity tax”) or die”. I’d happily volunteer my services for this task.
