The... 'left' have been... 'played'. For a long time they've been 'nudged' and 'pushed' into 'stupidity' by people far, far, smarter, well-funded, powerful and influential than they are.
It's rather sad. Identity politics and gender, the colossal importance of the 'individual' have been blown way, way, out of proportion, deliberately shoving class and economics aside and prodding the 'left' up a blind alley.
