I’m not advocating for people to accept the lesser evil, I’m asking them to understand that their vote is no longer a form of acceptance
This is a fun rhetorical trick, but I'm not interested in playing a semantic game over the definition of 'acceptance'. This:
A vote in the presidential election currently only holds the power to slightly shift the current power between bad and worse
is absolutely advocating for the lesser evil. Fine if you don't want to call that 'acceptance', but what I'm pointing to is not the choice itself, it's the act of advocating for it to begin with. Spending any amount of energy trying to convey the importance of voting for the moderate wing of fascism is a distraction from the message that both parties pose an existential threat to the working class. If your goal is to build support for radical systemic change, then there should be no ambiguity about what actions are necessary to achieve it. To use your bullshit trolly problem analogy- the 'two tracks' forced choice is a distraction from the fact that we need to stop the fucking trolly. Even if we end up pulling that lever in the end, you will never get enough people to get off to help derail it if you keep ensuring them that the worst will be averted even if they chose not to.
You can't build a popular movement against the democratic coalition while openly admitting that you have no choice but to support them no matter how aligned they are with the fascists. Liberals will continue happily existing in the status quo until it's made clear to them that their privileged position within it is threatened along with everyone else's if they choose not to act.
