You’re completely missing the point of the trolley problem:
Do you take an action that causes a direct harm, even if it’s in service to reducing harm?
It’s a valid moral stance to decide you will not personally perform a harmful action. That’s not walking away from the trolley, that’s refusing to throw the switch.
Your framing of the situation is false. Voting for Harris is throwing the switch and dooming Palestinians. Voting third party/not voting is not throwing the switch: you are not condoning the system that runs people over, you are not taking an action that directly harms people.
To be clear, throwong the switch is also a valid moral stance.
Personally, I believe voting for Harris prolongs our faulty political system. I voted for Kerry, then Obama (first willingly, then let myself be guilted into it). The Democrats have only gotten worse with time, and I won’t vote for a party that represents me less with time instead of more.
Out west, country folk fucking love ranch. Especially with pizza.
