Your entire post was predicated on an assumption about the level of support.
"weirdly defensive"
It is neither defensive or weird. A lot of Americans in particular are grossly misinformed about {broadly gestures at almost everything related to this}, but they have very deep opinions. It's actually telling that you tried to portray the inverse (e.g. Canadians talking about America), when that simply isn't true: We are overwhelmed with American news and political happenings for time eternal, in media, news, social media, etc, where most Americans have a very superficial understanding of Canada for obvious, practical reasons. DHH's post panders to an alt-right crypto crowd, but to every Canadian it looks like ignorant clowning.
"You are also coming up with tons of ad-hoc explanations for everyone"
You're injecting a ridiculous number of strawmen. I argued against your statement that political positions on a vote = actual reasoned opinion. That has never, ever been the case in Canadian politics. No rational person expects it to be the case.
"agreeing wholesale with suspending the charter"
And with this statement, everything you've said on this entire topic has been completely discounted. The emergency act does not upset a single charter right. Not one. As with DHH ridiculous claims about martial law, it betrays that the speaker's hysterical take can be ignored as baseless rhetoric.
Further, the root post nowhere claimed "all Canadians support this". They noted that our base values are different and that many Americans aren't fully informed, and that is 100% true. As you've done with my posts, you're bizarrely spinning that out into something completely unsaid.
