Well, they didn’t say you’re not Canadian

But saying “a Canadian would know that” is necessarily insinuating that they are not Canadian for not knowing a fact. Which regardless of if the person did know the fact, is a ridiculous criterion to determine if someone is Canadian.

Furthermore, to suggest that Trudeau’s views aren’t synonymous with the Liberal party, ignores a big part of reality. That the party leaders wield incredible amounts of influence within their parties. If anything, party leaders are perhaps the physical embodiment of a party.
