Well, the electoral college isn't actually FPTP, it's even worse than that.

I don’t know what country you are from or how your voting system works. But I will guess that your country has many parties and after the election, a governing coalition is formed.

In the US voting system, similar parties get punished by stealing votes from each other. So, in effect, we have to form our coalitions before the election and choose the single candidate that will stand for all of us. So, you can think of the Democratic Party as the Democratic Coalition, made up of some truly left-wing factions, as well as some not very left-wing or even centrist factions, and so our candidate will be much more watered down than what you’d see in a different system.

You said it yourself, they are less far-right than Republicans, so Liberals get to pretend they are punks and rebels despite supporting the status quo.

Easy. We set the FBI on all the actual leftists decades ago. So the movement is having to slowly rebuild itself in the US. As a result Progressives are the farthest left things most Americans have experience with.

basically, the US is a one party system, but it has two parties

Libs are seething at this absolute correct take. If you're pro free market, you're a liberal and thats as 'left' as you'll ever be.

It sucks. Liberals will be blaming Arab Americans going to Jill Stein if Harris loses, rather than Harris and Biden, just you wait.

Sankara too, holy moly

Marx and Engels were called "authoritarian" so frequently by their contemporaries that Engels wrote On Authority. What's considered "authoritarian" is a moving target, an arbitrary line in the sand just for people who succeed in revolution, or at least in throwing off western Imperialist powers.

If your argument is that Marxism isn't Leftist then that's hilarious

I'm sorry but like, look at his beard. I'd date Marx
