One needs “bon mots” on occasion. “Communism is cannibalism, barbed wire, and the Gestapo.” That’s my take. It’s a variation on Churchill’s summation of the Royal Navy as “rum, buggery, and the lash”.
Take two: “Communism is a hate crime.”
I already know that “revolution is the opiate of the intellectuals”. My point here is that well meaning people will simply DROP any association they may have, with any people or groups who advocate, albeit often implicitly, the crime of Communism.
Communism is a horror. It is vicious men and women killing defenseless men, women and children. There is no good there, and much evil, no matter what apparently harmless intellectuals may say to the feeble minded.
