there’s no way anyone could help the fascists more than an ‘opposition’ party which routinely fails to actually oppose them
Yes there is. By actively discouraging opposition to the fascists, which is what you're doing. You are literally delusional.
if the democrats had any principles and actually opposed fascism they wouldn’t spend so much time punching left
I'm not even saying you're wrong about the Democrats; I'm saying you're wrong about motherfucking GAME THEORY and MATH! Even acknowledging what you just wrote, YOU STILL HAVE TO VOTE FOR THEM ANYWAY!
