"Why would you treat this group of protestors so much more harshly than ones that, say, block railways?"
Me? I found the railway blockades intolerable lawlessness. Trudeau took well-earned criticism for the soft-handed approach to them, and it cost him a majority government. It had far less of a negative impact on Canada (and touched on a very sensitive aboriginal issue), but those of us with actual value-based positions -- instead of just tribalistically flexing our positions to justify whatever we think "our" group are doing, as seen by DHH here -- are pretty consistent on this.
But can you point out any other protest in Canada that set up hot tubs on city streets, abused commercial vehicles and commercial privileges, terrorized residents, squatted on city parking lots as command and control systems, and operated a lawless zone? Pointing to some CHOP in the US (also GROSSLY unacceptable) isn't an example. Pointing at BLM isn't a counterpoint.
"expect them all to behave like their some sort of hive mind"
Among any group there will be bad actors. The constant citing of a Nazi flag appearance was just boring nonsense...at least until I repeatedly saw Canada First and Red Ensign flags (which are a subtler way of saying the same thing). QAnon nuttery would be just some fringe...if it wasn't the majority of content on their main stage and repeated by the main organizers constantly. The guy saying the flurry of incredibly ignorant misinformation would be just some nut, if it wasn't the same thing that came out of almost every participant's mouth.
"I also think your news sources are a little biased."
Sure. I mean, my news sources don't involved many QAnon blogs, but during the protest I had a video window playing most days featuring one of the sympathetic live streamers who constantly walked up and down the protest, interviewing participants. ZOD, the travel fun guy, some machine guy, etc. It is the words of the participant, and hearing their rhetoric at their stage, that gives me my opinion of this group.
