Only a few things need to be said about the CBC's Facebook experiment. Three of the top five wishes were religiously motivated. It looks like there is a remnant in Canada after all (1 Kings 19:18).
Wishes 2 and 7 are not wishes of themselves, but counter-wishes. They were created only after someone wished against gay marriage and abortion. These counter-wishes only serve to highlight the true wishes, the originals.
With regards to abortion, as pointed out by John Pacheco, there is an error in the CBC's coverage. Environics conducted this poll in October of 2006. This poll suggests that 54% of Canadians do not support abortion beyond the first trimester.
There is no end of vitriol coming from the pro-choice side. I am not going to link to it here, but if you need an example go to Choice-Joyce's blog. It's interesting that she considers the CBC's contest "stupid." This is apparently the real reason for the lack of action by pro-choicers. Presumably, they didn't want to sully themselves.
Given the results, I am not surprised that the CBC limited their coverage of the contest. No doubt the powers-that-be feel the contest was a PR disaster. This is where the Internet and YouTube come in handy. It doesn't matter when the footage was actually aired. People will be able to watch it whenever they want for a long time.
