You’re misunderstanding the post imo

It’s not that it’s impossible to make change with non-violence/playing fair…

it’s that making change against something as violent and unfair as the system is, with non-violence and fairness, literally impossible.

The tolerant need not tolerate the intolerant.

Your chances of wining fairly against an opponent who’s allowed to cheat and change the rules of the game decrease the more your opponent wins.

Vote for who you believe in, protest against those you don’t. Hedge those bets, everyone else is.
