In fact, the America in "Make America Great Again" isn't some antebellum slave factory at all, it's the America before the loudmouthed social activists embarked on their campaigns of lies, bullying, and social and physical destruction. It was the America that still had a vestige of religious toleration, of increasing racial comity, of the lack of the politics of resentment and hatred. We're going to have to fight to get that America back, and it's high time we stop being nice and do so.
Methinks that she is one of those Lefties who thought the "browning" of America was all but complete with the election of Hillary Clinton via mass amnesty. She is moaning about soar grapes.
