Probably because 2/3 of the population can't be reached. They either want to do whatever they can to be anti-left, even if it hurts themselves, or they don't care at all. So voting harder isn't going to work. All while education is being gutted. I honestly don't know what other options are left. Maybe turning states into their own countries and let them raw dog the world without any help from the federal govt. Idk, it's bleak.

I find it mostly with younger people steeped in ideology and dogmatism, that reparations need to be made for a long history of imperialism.

3rd wolrdism also exists in Europe. I'm pretty sure it's far more popular.

The reason why they feel overrepresented in the US is simply because a real, progressive leftist political project is essentially impossible, so the most extreme of the extremes are proportional more audible.

It's quite frustrating, but it's clear propaganda spread. There's a complete vacuum of media for leftists in the US, and a tiny amount of money goes a long ways to cementing desired propaganda. Seeing the entire left in the US turn on Ukraine calling them Nazis, when in fact they were occupied by Nazis, with all the terrors that entails, and were planned to have half their population killed and the other half enslaved to Nazis, well, it's red pilling. The left in the US is so weak and leaderless that it is easily co-opted to any sort of end.
