If just posing this question irks you just think of it as an excuse to explain to your more right wing fellows why progressives would be in support of more women in the executive than less. Alas I can only think of one reason to consider more women in a conservative cabinet to be good thing. Representation is a good in and of itself in democratic community.
But that being the said, where are all the brown people? If it is a question of representation as a good in and of itself then surely the parliament in general is a perfect reflection of just how excluded non-white minorities are from political representation in the Canadian democratic system.
