You cannot really have a working left made of brocialists beating everyone else over the head and identity slash sexual politics warriors attacking everyone in sight in a world where billions still starve. It’s a joke and nobody much will take it seriously
The other problem the American left has, and let me put this kindly, is that it’s racist and misogynist as shit. It’s a left in name only, enacting the same old toxic supremacist and patriarchal values mostly. Hence, it’s impotence.
