I don't see an anti-Christian card being played here.  I see the Liberals trying to define the new Con leader on their terms, much as TheHarperParty was successful in defining a series of Grit leaders on their terms: Paul Martin (Mr. Dithers); Stephane Dion (not up to the job);  Michael Ignatief (he's not here for you).

Naturally, and somewhat ironically; it is the Cons who are playing the religion card in an attempt generate some pushback.  The Con base - and most of their caucus - are willfully blind to the fact that in a pluralistic society a religious orthodoxy cannot be allowed to enlist the state to enforce their particular moral views.
