There's only two people who I have ever seen that harbor this mentality:
- Enlightened centrists who think saying things like both sides bad makes them looks smart and pretending to be an "independent" thinker who's always in the center makes them feel smart
- Far left extremists who purity test EVERYTHING and think anybody to the right of Mao is a neo nazi.
In both cases, they provide nothing of value to the discourse. Enlightened centrists are politically apathetic, and they only want to feel better about themselves by putting down "the sides", and far left extremists are not serious people because they're inherently irrational and dogmatic. There's no appeasing either of them nor should anybody try to. Most people are pragmatic enough to understand the point being made in these meme, but these dingleberries won't.
