All these things have been derided as "politically correct" in my lifetime (and therefore a bad things): "You can't make a joke these days", i.e. you will get an earful if you make sexist, homophobic or racist jokes. "You can't give a woman a compliment these days", i.e. you can't engage in wanton sexual harassment. "Education is too politically correct these days", i.e. schools teach a history curriculum that recognizes and is critical of imperialism, racism and the like.
In my 30-odd years of life I don't recall it ever being used in the way you describe, but it could predate me.

i see, i guess my understanding was different, i alway perceived it as the opposite; pc equaled limits on speech or conduct that went against the majority groups or what they wanted, in my understanding, but it seems that was probably wrongthanks for replying, i appreciate it!
