Voter apathy, not everyone votes but the crazies are more motivated to do so generally. Plus conservative brainwashed upbringing =/= religious automatically. Plus the American owned propaganda drip feeds they all consume. They believe enemy state media over their own country. Federal Liberals do nothing to prevent this.

We were about 50/50 last election with Calgary fucking us over with FPTP giving UCP the majority, who are Maple MAGA and aligned with the Christian Heritage Foundation, MAGA, and Christian Nationalists groups like Take Back Alberta. Now we have CIA PsyOP campaigns too as USA tries to destabalise Canada by fueling seperatists.

None of this is organic. The province is heavily manipulated.

A large portion of fault is assigned to Jason Kenney who merged the progressive conservative party with the regressive nutjob party called the Wildrose in order to keep winning elections against a strong centrist "NDP" in name only provincial party. Then he had a tantrum and quit after barely winning a confidence vote as the crazies took over the merged party. Now he speaks out against UCP from the sidelines constantly after getting a golden parachute job with ATCO after he deregulated utilities as if it's not his fault. A very dumb, short sighted corrupt unChrist-like Christian is his legacy. A useful idiot. A man with no history of any women in his life and has a brother who ran a gay conversion "therapy" camp. Jason loved to harass gay couples by trying bar loved ones from seeing their dying partners in hospitals when he was younger.

2021:

https://www12.statcan.gc.ca/census-recensement/2021/as-sa/fogs-spg/page.cfm?lang=E&topic=10&dguid=2021A000248

Religion: In 2021, the top religious group was Catholic, with about 833,025 persons representing 19.9% of the total population. The second group was Christian, n.o.s., with about 429,380 persons representing 10.3% of the total population. The population who declared no religion and secular perspectives numbered 1,676,045 persons, representing 40.1% of the total population.

2nd source:

The largest faith in Alberta is Christianity and about half of the Alberta population (48.1%), reported that they were affiliated with a Christian religion. Non-Christian faiths account for 11.8%, and the remaining 40.1% are classified as unaffiliated, which can mean agnostic, atheist, or “nothing in particular.”

With immigration, there were growing proportions of the population who reported religious affiliations other than Christianity. These religions included Muslim, Hindu, Sikh, and Buddhist.

Indigenous and smaller faiths are a minority and account for 1.3% of the Alberta Population

"Allo, this is Statscan, can you tell me what is your religio-"

"Onetokebekici, tabernak, je vas cahlis-"

"Okok merci, I'll put down Catholic, buh bye".

Yea, there needs to be an "other" category in the very least. Otherwise I think the data isn't super meaningful.

I don't think every study can/should enumerate every possibility. So when they don't have an "other" category it forces findings into the wrong boxes and becomes misleading.
