I’m not that hopeful that the left can change the system from within, to be honest, I’m just certain it’s too late to think about that because under fascist rule, not only will things not improve, but many of us will face genocide.
The time for leftist change was 20 years ago, or with any luck, 8 or so years from now after the fascist threat has been quashed. Right now we have to think about unifying like it’s 1932.
