I don’t think any both siders are around right now in America that aren’t right wing.
In saying that, this post and your comment are examples of the left today being excessively socially authoritarian which labels anyone who doesn’t completely conform the enemy.
“bothsides” is by the majority of people in reference to the two political parties (in reference to america), not left wing and right wing in a political ideological sense. As you said both political parties operate within a system of opperssion fighting for control of power. Neither side is good, but one could say that one side is definitley more damaghing than the other in a realist sense.
i think though from my experience, today the left, specifically, moderern progressisvism has become far too socially authoritarian, as an arnarchist type i cant abide by any authoritarianism and the left is no stranger to it.
