I always find the Canadian independence thing is good for a chuckle.

Care to explain that?

Why the hell should I have paid any respect to some actor/president who used an astrologer to help him make his decisions, openly joked about nuking other countries, thought that a "limited nuclear war over Europe" was a good idea, and the myriad other ridiculous things he said and did?
I don't excuse certain Canadians' actions during this time. I still feel nauseated by video footage of the "Shamrock Summit" where Brian Mulroney and Ronald Reagan sang together on stage.
As I said, some of this "pop culture" stuff is really a generational thing, along with the facts that I don't watch much TV, haven't seen many movies from the last 15 years (grudgingly watched the nuTrek crap to shut up the people on TrekBBS who kept trolling me), have basically ignored Facebook after a former friend suddenly started posting some rather nasty stuff including links to people who want the premier of my province assassinated, and nuked my own Twitter account after it was hacked. I'm not willing to go through that hassle again.
Yes, we're inundated with American media and TV/movie "culture" and I pay little serious attention to most of it. Make a Seinfeld or Futurama or Hobbit/Lord of the Rings reference and the chances are that I won't have the faintest idea what you're talking about.
And there's nothing wrong with that.
So do forgive me if I didn't immediately understand the profound message of that ridiculous "ironic t-shirt."
