love it when anarchokiddies hate the very idea of governments existing so strongly that they blind themselves to reality :/
You can provide an anarchist everything they'd ever need to realize that [insert government] is objectively supportable, and they'll prefer the non-source that supports their bias instead.
You can show them textbooks upon textbooks on the genuine good China is doing in the world, they'll point you towards a hit piece that was likely written by the CIA to disprove you. You can tell them about the wonderful things Cuba is doing with medical internationalism, and they'll point you to a still image of protesters taken out of context.
Just because the government they grew up under sucks, they choose to believe that all governments do. And refuse to accept that their bias is dead wrong, and their aversion to "statist" politics only hurts the left.
