Some day, you'll appreciate this opportunity to quit filling your head with nonsense.
The goal of political correctness is to silence opposition through various means, including diversion, shame and ridicule, irrespective of the extent to which the opposition is well-founded.

The truly principled should gird themselves in preparation for the slings and arrows that lie ahead in the new year. This bit of advice will hopefully help.
