So, my strata complex banned smoking earlier this year. It was a bylaw adjustment that had been proposed pretty much every year for the decade+ I've been in the building. It was voted down, year after year, until this year. This year, the group that wanted to ban it, just happened to get the right mix of people in the AGM to pass the amendment by 1 vote. A bunch of the pro-smoking sorts (pot heads generally) had grown tired of constantly voting it down, had assumed this years vote would go the same, and didn't show up.
Attempting to rescind the change is nearly impossible, especially as the 'indifferent' people in the building generally just prefer to vote for the status quo, whatever that happens to be at the time -- and as the younger generation that increasingly moves in, has been taught smoking is unequivocally bad and anyone that does it is bad.
The point is, that whether its right wing or left wing, a progressive or conservative movement, persistence can yield results, even if you don't change your approach / message at all -- you just need to wear down the undecideds, and wait for just the right mix of voters, to completely break existing norms to a point that they can't be rebuilt.
Hell, just look at the USA as a case in point. Extremist elements did their thing. The separatists are now moving to likely take over the whole conservative party in Alberta, by controlling a majority of the 'base' supporters. So, no, the separatist "madness" won't go away.
Especially because, at its core, there are justifiable reasons for western provinces to feel alienated/like an afterthought for the rest of the country. Even BC's conservative party is moving towards separatist motifs. BC has 43 seats in parliament -- with about 13-14% of the Canadian population. The Maritime provinces, all combined, have about 5% of the country's population, and like 32-33 seats. A riding in BC's lower mainland tends to have 120k people in it -- ridings in PEI have less than 50k people. A BC voter is far less represented in the house than voters in the maritimes. The Maritimes are ok with this, because they like having outsized power for their actual size/contribution to the country -- few people would willingly give up power, and they're no exception. The Liberals are ok with this, because the maritimes are one of their core electoral power houses. The people in power, who often moan about equity and inclusion, would rather leave the imbalance in place and make out like western alienation is a fiction -- which just feeds into the cycle of alienating the west.
