American "liberals" are communists. Therefore they ignore the democide and genocide that communists commit. Stalin, Mao, and Pol Pot (for example) get a pass because communists protect each other.
Communists and National Socialists hate(d) each other because bloodthirsty totalitarian tyrants don't like competition. This is also the reason for communists promoting the false association between the National Socialists and the "right wing".
By all means. Do the f#$%ers.
