Racism is counter-productive to democracy with equal protection of the law for all citizens, yet free speech is important too as is freedom of assembly. Hitler led the Nazi socialist party, Stalin was a communist and the American left united with the globalist left not only use violence against political opponents, they also use the push-button tool of internet information controlling, directing, and sabotage when they can. They are not a neutral, just suppoort the U.S.A. element and apparently work to force the U.S.A. into their idea of the ideal globalist lackey stooge state.
