You haven't been around these activists a lot, have you?

Their entire thing is to chase that high of having some struggle that makes them feel morally superior. So the most extreme, sanctimonious position becomes the goal. When someone else writes it, it just affirms them in their belief of being an important part of positive change in the world and will updoot it without thinking. Over time, as they sail past reality again and again, this destroys their capacity for rational thought.

Effectively, you average activist becomes an addict for asinine opinions.
