I know HRC made her "deplorables" comment in Sept 2016, and this was a badge of honour for them.
I'm also familiar with the "Know Nothings" political party from the 19th century, religious cultists, conspiracy nuts etc, but was there something brewing in American culture prior to TFG, where stupidity trait morphed from shame to indifference to pride?
Or can it all be laid at TFG's feet?
