So, you've given up on McKinley, Harding, Wilson, and Coolidge.  That's smart.  But, look - Truman, even as a young man out of military service, was not a racist, was pro-catholic, was pro-Israel and pro-Jewish.  As president, Truman integrated the armed forces by presidential decree.

You are letting the RNC use you.  Republicans have used racism to get the Southern white vote ever since Lee Atwater invented the Southern Strategy that got Ronnie Reagan elected.  Trump has made that racism blatant.  The RNC propaganda organs for years have been accusing Democrats of what they know themselves to be guilty of - cheating the poor, appealing to bigots, running up the deficit to enrich the few who are already rich beyond imagining (like Trump, or Romney).  Only the weak-minded, ignorant, incapable of thought, unable to see which side of the toast has the butter on it, and vulnerable to any message repeated often enough, whether true or not, will swallow the noxious swill from the RNC.
