EXACTLY the WRONG thing to do. That's how PC got into power ... cause no one took it seriously at first. Now we could conceivably lose our country because of PC. You HAVE GOT TO GET IN THE FACE of ANYBODY or ANYTHING PC. Shout it down, knock it down, beat it down ... cause if we let it show it's ugly head again WE WILL ultimately lose.
Very sober advice for us all. PC is the means of the socialists to control our country...into oblivion.
IMHO, subtle, amused disbelief works well because it causes them to privately question their own beliefs.
To each his own, as long as we all resist political correctness in our own way, we will make gains.
