What nonsense like this does is focus on a small aspect of overall human traits and then attempts to make generalizations to promote an ideological agenda.

Bias is a valuable evolutionary trait and judgement is a fact of life.

You get dealt a hand of cards when you are born. You may have an "introvert" face, but you might also have an above average IQ. "-isms" are cop outs that play into a victimization narrative that is then used to drive political agendas which ultimately are not beneficial to the supposed wrongs they attempt to remedy.

This is a limitless world, and don't let fluff like this rain on your parade. Get up, get out, and get doing. Enjoy the knocks along the way, and if you are inclined to feel the underdog, use it to prove 'em wrong.
