Maybe it's a minority of Liberals that are walking the self-righteous line, but it's a loud minority, with huge platforms from diverse areas, that are policing the open dialogue that could and should be taking place.
As a moderate Republican, I could get on board with Democrats. I am for strict gun control, LGBTQ rights, healthcare reform, global warming, Wall Street regulations, etc.. But it's become impossible to associate myself with a party that openly doesn't care about white America.
FWIW, the Republican party also showed me that they no longer care about conservative principles.
Ah yes, who will look out for the poor, disenfranchised white man in America?
