Well, if most people in your circle of friends agree, then it must be a universal truth! How silly of PotD to suggest otherwise!
(That was sarcasm, by the way)
That's not overly unexpected. Fundamentally, the Green Party is based on the philosophy of telling everyone they suck and need to do better and make sacrifices for the sake of the greater good. That's not a popular position, especially not in the 80's (environmentalism has become much less niche since then). The PPC, on the other hand, is based on a philosophy of telling a small subset of Canadians what they want to hear (that the country's problems can be blamed largely on crazy progressive principles like treating immigrants as legitimate people), which is going to be very popular among that subset (especially where said subset has generally been ignored by everyone else).
Quite simply, the PPC didn't perform poorly because they were new. They performed poorly because the vast majority of Canada doesn't care about what they have to offer. Their voter base is united by ideologies that have been trying and failing to gain traction for decades, which means they aren't likely to gain much by way of popularity moving forward because those ideologies are still going to be struggling in the next election, and the one after that.
The only thing about immigration I seen from the PPC is that they want to slow it down. And in times like these I believe that's a good idea.
Can you show me where they dont feel immigrants should be treated like people?
