We're not immune to it. I live in a conservavite run province (equivalent to you governers) for another 4 years because of the exact voter apathy that led your country down this path. And the province will regress in many ways as a result. But federally at least, enough Canadians realized last election that although our liberal leaders aren't making as much progress on extremely important things like climate change, we've figured that some small/slow progress is better than regression. Until some of y'all realize that, you'll forever be stuck having purity discussions while your rights are stripped away. 2016's consequences are forever unless you all work really hard to get past this kinda nonsense over the next 8 years and improve things. Like the recent gun legislation, small steps are better than no steps and more candidates on the side of those not wanting to regress can lead to even more steps forward. It's just going to take a lot of work and compromise to get there.
To this note, republicans fought for 50 years And slowly chipped away at abortion rights. Are people on the other side of the issue as committed?
Unfortunately I'm not hopeful for that.
