The Liberals (a/k/a Progressives) are always preaching “diversity”, but deep down they really don't want everyone to just look different, they really want everyone to think like they do. They are the chief proponents of “political correctness”, who will determine what you can say or do, and will have the unelected P.C. Police “sworn in” to carry out their destructive attempt at conformity.
When a liberal is offended by what is said or done, he/she doesn't just complain or offer an opposing view, they want their “pound of flesh” by calling for for that person or group to be fired, and if that offending person is in the media, they want his advertising sponsors to boycott the “offender” to further their desire for compliance to the liberal orthodoxy. How divisive and exclusive are those tactics?
