It's not as funny when you get to live under the rule of well trained Marxists. Hundreds of millions of them have been produced over the last century. Look into a history book or just ask around.
That people in the US espouse Marxist beliefs while a Marxist state commits genocide is “the same” as when parts of American society supported Nazis.
Disney thanking China for their help filming Mulan next to a camp is the same simpering we saw from corporations supporting the Nazi regime.
