When has the US actually overshot left though? There was a short period of social justice awareness, but that didn't translate to actual leftwing economic legislation. Even protests and movements with left wing goals were co-opted by the nominally center-right establishment and neutered.

This both-sides stuff gets me, man. Our history is by and large very right wing and every time there's a flutter of left leaning ideas, people chalk it up to some far-left political success and therefore the far right backlash is deserved, as if things ever actually went left in the first place.
