Hm. Three things:

First, their "single plank" is also the sole plank that supports us all; you'd have to be a complete idiot to deny it. It's also a plank that the other parties give lip service to (and yes, that the NDP is better than the Libs or CAs on). And that plank is rotting. If it gives way, you can have all the social progression you want but it won't mean squat.

Second, I don't know who's spreading the rumours that the Greens aren't socially progressive (the NDP, maybe?) but I don't see it. Maybe I'm socially conservative (nah), but their platform dovetails quite nicely with my own views on a range of issues. More so than any other party. And in the absence of the necessity for strategic voting (I live in a riding where all non-Alliance votes are "protest votes," all other parties combined not coming within leagues of the winning party) I feel very good about having the option of voting close to my conscience.

Third, the Greens will never make up a government; they may not even ever make up an opposition. But a couple of Green MPs would go a LONG way toward pushing the other parties in the direction of more aggressive responsibility toward the environment. That tired old plank.... :)
