Not up to the challenge
Last week, the House of Commons rejected a bid to open up a conversation in Canadian politics on when human life begins. Give some credit to the collective wisdom of the chamber -- it knew what it couldn't do.
Regardless of where you stand on the abortion issue, there's one main reason to applaud this outcome: Canadian politics, as it currently stands, has not proven itself worthy or capable of such a discussion. It's beyond the skill set of the participants. Have a look at some of the headlines this morning, particularly the second one.
If these headlines don't persuade you, have a look at what happens in the Commons every day, particularly the 15 minutes before Question Period (partisan members' statements) and the 15 or so minutes afterward (complaints about how QP unfolded, in points of order, etc.)
Then ask yourself: Do you think the Canadian political class could have been trusted to have serious, measured debate on such a massive question as when human life begins? I think we know the answer to that question.
