For one, many Albertans who would otherwise be your allies are now offended.

Meh, I kind of agree that the parent comment is needlessly antagonistic but I doubt that this would be the thing that tips someone over, someone this easily swayed would have found other reason to not be an ally already.

So agree on “making the situation worse rather than better” because it degrades the discussion, but it’s not like being offended by this will meaningfully change someone’s view on the matter.
