It’s another term that has come out of the university liberal arts departments. Another one is moral relativism. The endgame is to rationalize why one group under performs another.
Or an old favorite: violence doesn't solve anything.
Thousands of years of history show us that violence literally solves fucking EVERYTHING. Being civilized is just knowing when it's needed and when it's not.
Old days, call a man a thief or a liar and you got shot. Because you didn't impugn man's character unless you REALLY meant it and were willing to back it up.
Nowadays, people can say anything and do anything because giving someone an ass-whipping isn't civilized and will only land you in jail.
