Respectfully I don't really agree that this is a thing. There is an element of discerning that a person is just a jerk, misguided, dumb, or just shitposting without consequence due to anonymity or whatever and learning to disregard their opinions as irrelevant. That is, a lot of internet randos fall into this category.

But I also think if people don't trigger a warning as someone worth shunning that their criticism affects us, especially irl.
