Overton window.
Obviously "left" vs "right" depends on the geography and time period. Otherwise, it becomes very hard to talk about politics.
You have some groups who have a far-left affects in the US, but honestly since the BPP and the Rainbow Coalition they are either ideologically weak or ineffective.
Imho this is 'normal'. Far-left ideals do not seem to work at large scale.
I thought far-left is typically vanguardist and doesn’t believe in any type of [real] democracy? Dictatorship of the proletariat and all that stuff..
Other on the far left will rather go a more local route, destroying state structure (as state is oppressive by nature) in the beginning to create a collective bottom up.
I'm not saying any of this is a good idea btw, it's just that far-left has fled the US a long time ago. If you aren't revolutionary, you aren't far-left.
(Because when supposed "far left" organizations use the word "empowerment", i just facepalm, that's "third way" bullshit imho)
I think Musk doesn't really understand his politics, and that's what hurt him. He should be in the extreme center (with Hillary, or Bush), but he was caught in ID politics for a long time.
