Sarcasmatic

Vaccine "skepticism" used to be more prevalent among the (mostly left) urban health freaks. But that is changing rather rapidly, see for example https://www.politico.com/story/2019/05/27/anti-vaccine-repub....

This might be a good example actually of people self-sorting into one of the two tribes. And Republicans (not conservatives) have conquered the science-is-bad spectrum so thoroughly they don't need to fear competition in the foreseeable future.

As you pick up on, the question was just used to make a statement, not gain information. That could be considered bad-faithy. But at the very least it annoys with its overused tone of sarcastic outrage, especially because it was the second such comment in the thread, made after the first was already shown to be entirely wrong.

On its merits, the accusation of hypocrisy is also a non-sequitur: from "one bad thing is stopped" never follows "all bad things are stopped". The implied expectation is impossible to fulfill.

It's also unhelpful, politically, in a way that this thread, HN generally, or even "the internet" are full of: If everyone is always assuming the worst while expecting the best, it removes all incentives for anyone in power to behave honorably. After all, if you're going to be accused to be corrupt and/or incompetent anyway, why even try?
