That’s not the point: voting is unrelated to the work of uprooting fascism. If you spend all your energy getting Biden elected, you are still no closer to solving the problem.
There is some credence to using that as leverage to get liberals (whose only concern seems to be getting their guy elected) to engage the actual work of eliminating fascism, but that’s not what I was advocating here.
Certainly not a prerequisite, no. The work that needs doing is no different in either case, and is met with hostility (of different scales, sure) under either presidency. Both will protect the institutions we seek to dismantle with force; one will simply be more open about it than the other.
For a leftist, neither candidate changes that reality. It will simply be more comfortable under one than the other.
