I haven't seen any thread on this issue, so forgive me if it already exists.
So what is political correctness?
At this point, I don't really see the point in trying to define it, all of us here have Google/Wikipedia at their disposal, and besides, members from Western countries most likely experienced political correctnes first hand.
I'd like us to debate its impact on society, if we should get rid of it or keep it.
Personally, I think PC is harmful. One example that comes to mind is when the BBC asked the British public, a few years ago, if any references to Muhammad should be accompanied by "pbuh" ("peace be upon him") to accommodate Muslim sensitivities.
Imagine the outcry if someone tried to get National Public Radio to alter all references to Mary, the Mother of Jesus, to "Blessed Mary, ever-virgin" as in fact she is referenced by some Catholics and Eastern Orthodox.
Also, PC culture seems to have devolved into a generalized form of Godwin's Law. Godwin observed that as any Internet argument progresses, the probability of a frivolous comparison to Hitler/Nazis/the Holocaust approaches.
The PC movement wants to transform us from being a society that values free speech, into a society that wrongly believes everyone has the intrinsic right to not be offended.
Even some Hollywood people find PC to be absurd:

'Oh, little snowflakes, when did you all become grandmothers and society matrons, clutching your pearls in horror at someone who has an opinion about something, a way of expressing themselves, that's not the mirror image of yours?'
