The Left is the true evil. How many lives have been exterminated because of Leftist ideology? Fascism is a product of the Left. Democrats in the South created segregation and Jim Crow. The KKK was manned by Democrats. Hitler borrowed from the Democrats in the South their ideology of racism. Nazi dogma against the Jews has writings that are word for word the writings of Democrat racists.
You imagine that segregation was somehow just a southern thing. Wrong. Also, Margaret Sanger was no southerner, eugenics policies were adopted and enforced by the state far and wide with what little resistance there was at that time being southern, it was regarded as "progressive" at that time, you see.
Question: who was "progressive" in word and deed in that era, and what did it mean? You don't appear to quite understand just who was what, and just who advocated doing what to whom back then.
