You twist words for no good reason. Trump is authentic because even though he’s a zillionaire, he writes what he thinks (and what he doublethinks, like his followers). Authenticity has nothing to do with the positive traits you adhere to it: one can be a veritable asshole, which doesn’t make them less veritable.

“PC speech” is also fully unrelated with granting respect and dignity to anyone: actions speak much louder than words, and the average safe-space builder who will yell loudly at a dean will in average prefer a Jeanne to a Latisha when she hires someone to work with.
