The first sign is subtle yet subversive:
I think the sign is meant to remind passersby that the Conservative Party is little more than a front for the Reform Party. The subtext is obvious -- the Conservative Party is full of fake Tories like Stephen Harper, Stockwell Day and Preston Manning. It's street theatre at its finest.
The second sign uses absurd humour to convey the homeowners' strong nationalism:
By hanging the sign sideways, I think they are trying to say that Gilles Duceppe and his separatist friends are out of kilter. Not that it matters. You can't vote for the Bloc in Ontario. Maybe the homeowners are showing their distaste for all of the local candidates and are staging a silent protest by hanging a Bloc sign.
Or maybe it's a backlash against the sea of Michael Ignatieff signs around here. Hanging a sign with Gilles Duceppe's face on it is a clever reminder that Quebecers are turning to the Bloc because of the Liberal sponsorship scandal. The homeowners' message -- don't vote Liberal.
Perhaps I'm reading too much into it. But it's more fun that way. Plus, it makes the neighbourhood seem way cooler than it really is.
