So:
politically correct
adj. Abbr. PC
1. Of, relating to, or supporting broad social, political, and educational change, especially to redress historical injustices in matters such as race, class, gender, and sexual orientation.
2. Being or perceived as being overconcerned with such change, often to the exclusion of other matters.

One is inclusive and the other is exclusive. Interesting!
Not as interesting as this little blog:

Apparently it's politically correct to poke fun at us Canadians AND Hispanics.

Canadians = Nationality.
Hispanic = Race

I believe it is universally understood that making jokes at the expense of someone's race is a no no. That, I believe, IS politically incorrect.

What is missing from that list:
Non- Religious based Public Figures (in General)
Belinda Stronach (In a class all her own!)
And...
Americans (Anything to do with)

Poke Fun of Canadians, please, we invite you to. We have a pretty well defined Comedy Culture in this country. We're used to being inwardly jovial!

puns anyone?
