The notion that Biden represents a lesser evil compared to the chaotic reign of Trump is a common argument. However, we must not forget that there exists a moral threshold below which neither choice is acceptable. To suggest that enabling a literal genocide can be considered a lesser evil is a morally bankrupt stance.
Saying that voting for Biden is a moral obligation to prevent the return of Trump perpetuates a dangerous fallacy. It implies that the democratic party is immune from scrutiny and accountability, no matter the atrocities they commit. This line of thinking allows for a never-ending cycle of justification, as long as there's somebody considered worse, the democrats are granted a blank check. This is nothing more than a form of gaslighting, manipulating the public into believing that their only choice is between two evils, rather than demanding a better standard of leadership and true representation.
You have received a lot of attention and information. What do you expect, for people to bend over backwards to talk to you about this on your terms? What person who takes learning seriously does this? Do you show up to a classroom and leave if the teacher does not re-frame their lecture on physics into the trolley problem? "Outreach" does not mean you change nothing about yourself and everyone else changes what they're doing for you. You could receive the ideal maximum of compassion, patience, and clarity of thought and word, but if you are only willing to approach it on your terms, then no matter what you tell yourself about your intent, the substance of your actions is that of reinforcing what you already believe, not learning.
And I am speaking from some experience here. I did not always have the views that I do and one of the most important things in changing that was doing more listening to people who are better informed. Philosophical questions like the trolley problem gives people a false sense of competence in understanding a given issue; that as long as you can abstract a problem to its component parts, you can overcome any ignorance of it and arrive at the correct position. This is not so. You must understand what is happening correctly, so that you can properly generalize. If your information on the fundamentals is incorrect, attempting to generalize will only obfuscate rather than clarify and give a false sense of confidence in your position.
