Anyone that believes the official narrative about it got cucked by Canada's MSM/Authorities & are victims of TAQIYYA.
The Canada Terror Attack was a conflict between Islamic groups for control. There were multiple attackers & defenders involved.
The narrative(weapons/weapon type/weapon amount, people involved, race involved etc) was shaped by the MSM since the beginning to get away from this factor, because it would make Canada look bad after Tred's pro-refugee comments.
Much like the Church Shooting, this was also backed by people that wanted to cause a Race War.("We need them to fight, kill a bunch of minorities in a place of worship & pin it on a white guy")
Before it happen, look what was in place before hand:
1) CTR 2.0 in place to AstroTurf the narrative spread & suppress anyone/anything that questions it.
2) Islamic-Left protest networks(with Soros backing) active & in place at key locations for disruption/attack opportunities.
3) A "Trump is bad for his 7 country ban & its making Muslims the victim" narrative going on.
Now look at what happened after it:
1) Mass sympathy & support for Muslims(To a point where places they worship got police protection, Laws possibly passed in Canada, etc)
2) Framing of the Right wing/Alt Right for the incident & more demonizing/censorship/cracking down of them.
3) More pushing of the "Trump is bad, Muslims are the victim", "White people & Nationalism is evil" MSM narratives.
