Read about it, here:
My party’s suppression of debate is the straw that broke the camel’s back. Today I am saying sayonara to my Liberal membership.
It’s strange to see the Liberals try and capitalize off of abortion support. When did they get this extreme?

They got this extreme when last election Canadians told them resoundingly that you have to be extreme on one side or the other to get elected. Hopefully they mellow out soon and get centred by the next election. Debate on the abortion issue is a little stifled in Liberal circles right now, but debating it within the party will resume again I’m sure.
As for being against the Conservative motion to discuss the personhood of fetuses, I am against them talking about it with the exclusion of all others as much as I’m against the NDP talking about it with the exclusion of all others. Don’t kid yourself, the Conservatives are very exclusive.
