The language laws are supported by all major parties in Quebec.
This cannot be stressed enough. I understand, us being mostly anglophone around these parts, but the reason these laws exist have their history and their purpose, and making the decision, even as an outsider, to vote for someone or not in this poll based solely on "anglophone bigotry" is shallower than shallow.
PQ are interested in silly petty games with the federal government to boost support for sovereignty and to play the victim a lot. They're also a (reasonably) progressive party that doesn't want to shaft all of the students with absurd tuition raises (PLQ) or starve the public sector, including Hydro-Quebec, for no reason other than ideological ones (CAQ), and are at least the most coherent and consistent of the three main parties (particularly, more than the CAQ).
At the end of the day, the PQ is a Social Democratic party with a Nationalist bent. That's all there really is to it. Sovereignty is almost certainly not going anywhere, and given that all of the other parties support the status-quo when it comes to language, the PQ isn't, effectively, going to be that much more nationalist in
policy than the others, aside from a few token anti-Harper fits. Let's all save the cheap shots (such as comparing them to Front National...) and stupid "Pauline Marois is just like Hitler, she hates us anglos, she wants to put us in camps, i'm no jew!" stuff for YouTube comments.
