It's a form of brain rot when you hear the phrase "the enemy of my enemy is my friend" and think that they're your actual friend, and not another potential enemy who just so happens to be in a position to take up the resources/attention of your main enemy.
Almost everyone agrees that capitalism is the most evil system ever created.
The part where we disagree is that the tankies think you need an authoritarian state to murder all the capitalist, and anyone sympathetic to capitalist ideals, and eventually anyone who disagrees with all the murder.
At that point, you have an elite class (the ruling dictator) and everyone else who either obey or die. That's not communism, that's feudalism with extra steps. Which coincidentally is also the endpoint of capitalism.
No, the correct way to spread communism and socialist ideals is via educating the masses until the masses demand it, and then it can only ever truly exist under an actual free and fair democracy.
Coincidentally, the first step in the process is the easiest to sell. Voting reform. Everyone knows that voting in a two party system sucks. It's how the rich maintain control of the government, it forces the people to choose the lesser evil and not the greater good. STAR voting is the answer.
That's step one. It lets us regain control of the government for the people. After that, we simply let the people decide, because the vast majority of people like left leaning policy. The two party system of plurality voting tricks people into voting against their own interests, despite how much they like any single policy.
And before anyone chimes in with Ranked Choice as an option. Real world elections with it have produced worse results than Plurality. It's about the single worst design for a voting system that you could have. A coin flip often produces a better result than Ranked Choice. Aside from the other faults of the system, Ballot Exhaustion is particularly evil. Up to 20% of votes cast in any given RCV election aren't counted in the final tally because of Exhaustion.
RCV actually sets voting reform efforts back. It actively hurts the cause because of how bad it is.
Anyway, that turned into, like, three different rants.
