Don't these people ever get tired of having to qualify themselves as 'not a facist' or 'not spreading misinfo' the second they sense their toe on the line?

No, it's a mandatory virtue signal. It asserts they are one of the group so they don't get their head kicked in. But because the Left are filled with resentful pieces of shit, they respond by saying "you're allowed to ask questions" as if questions were allowed when they might result in dissent from the narrative.

This question in and of itself would be labeled "vaccine hesitancy" on Facebook and require immediate action against it.

"You're allowed to ask questions." No, you're not. You don't punish and silence people who are allowed to speak.
