i want to clarify my point, because it's the same thing that just happened in the united states and i don't think it's being understood very well.
what the liberals are doing is attaching minority representation to establishment politics, so that when voters see a minority candidate they immediately assume that this person does not represent their interests, but is essentially a pawn of the party and by extension the banks. it's classic blowback, because it's rooted in the racist assumption that minorities don't care about politics, and just vote on identity.
what they thought that they could do is fly in all of these minorities and just use them as a cover to push through their right-wing agenda. the thinking is that they can get away with a lot more when it's being done by asian woman and black men than when it's being done by a bourgeois elite of white men. so, they selected the minorities that did exactly what they were told by the party and then promoted them as replacements for dissenting voices. at the end of the day, the corporatocracy gets it's pipelines and tax cuts, all while voters are patting themselves on the backs for increasing the diversity of parliament.
what they've done, instead, is install minorities as the face of the establishment, and create the perception that minority candidates do not represent the interests of voters, but instead are working for the political elite.
this is what actually happened in the united states during the obama administration (although it started happening during the clinton administration, and the bush administration actually used the same tactics). people started to notice that the government consistently sent minorities to do it's dirty work. so, it came to be that they started voting against minorities, in order to try and protect their own interests.
if the government continues to use minority groups as a way to gloss over it's right-wing agenda and push through unpopular measures, it's going to create the same backlash. we're already seeing this happen, internally, at the riding level. and, while it may be a necessary reaction to bone-headed government policy, it's not a can of worms you want to really open.
the government needs to change it's strategy before it creates a mess - and we need to be clear in assigning blame where it belongs, here, which is in the pmo.
