Can we have a rule? Anyone who compares all Republicans or all conservatives to Nazis is morally equivalent to a Holocaust denier. I'm willing to extend the same to those who compare all liberals to communists.
It is profoundly unserious, at best, to engage in this bull****. The Jews were not rounded up and gassed, the gypies slaughtered wholesale, Slavs tortured, raped, and killed in numbers greater than the Jews (who weren't looking at minimal casualties, you know?), because of the Nazis' (National Socialists, I might point out) stands on abortion-on-demand or marginal tax rates. Comparing the two is the work of either an evil, or a diseased, mind.
