The leftists have become a corpo/billionaires shills since occupy wall street happened.

Since 2012 the left ceased to exist in the mainstream. Class issues that the left raised before the takeover ware replaced by identity politics. Labels were introduced and Massed Formation Psychosis was initiated. All dissidents of even a slightly different opinion were attacked/cancelled en masse. Freedom of speech, religion, was now seen as archaic, nuclear families were seen as dangerous, racism and segregation were accepted ect.

Psychosis reached it's peak in 2020 when people had more time to reflect on their views in their time of isolation from coronavirus and subsequently more and more people were coming to their senses.

The scales are starting to swing back but in my opinion due to the sheer momentum of people waking up this will have catastrophic consequences for the western civilization.

Currently still there are no sensible/uncompromised leftist movements left and the only alternatives are on the right. And, like I said above, this will have catastrophic consequences.
