Those with unearned privileges often spin things as 'political correctness' to further silence those they wish to oppress.
Saying something is 'politically correct' is often a way of dismissing the voices of the oppressed.
It's not 'over-sensitivity' to ask to be treated with the same dignity and respect shown to others.
Wherever in the world a country is governed by spiritually ill, politically empty, ethically rotten and mentally stupid people, over there you can find nothing but chaos, tears and fire!
People often call fighting discrimination being 'PC' because they don't want their own unearned privileges challenged.
