I highly doubt that the United Nations would expel Canada for legalizing marijuana. And if you do, I'd like some of what you're smoking!
The main reason that I doubt that Canada would be expelled from the UN for legalising marijuana is because Iraq hasn't even been expelled. Nope, not after the Gulf War, and after Saddam allegedly poisoned and gassed his citizens.
Homosexual marriage is the next logical step forward for a country that prides itself on being the 'land of the free'... Why not make yourselves free-minded as well?
In my opinion a previous poster was correct when he said that a priest should not be compelled to marry anyone that he/she felt should not be married - Canada's own proposed legislation allows for that and respects religious ideals.
