Do you actually think the same number of people would die under Biden or Harris? Assuming your comparison is entirely correct the conclusion implies a singular choice. Fighting the entire system can happen in every scenario. If voting for the lesser of two evils is able to reduce the harm to a few people or buy time to fight the system then that seems like the better choice. Mussolini only caused the deaths of thousands, not the millions Hitler did. Maybe at that level those are just statistics, each and every person between those numbers has friends and family that would disagree.

“While evil triumphs and your rigid ideals crumbles into blood stained dust the only victory afforded to you is that you stuck true to your guns”.

I despised Biden and Harris. Voting for them brought me no joy. However I can say that I am already seeing additional harm being done that was not before Trump won.
