Nobody is going to make you vote one way or another, but please recognize the following:

The United States is currently a two party system. It sucks. We need to push for more ranked choice voting, as well as direct popular vote.

However, until we're able to achieve something that makes this parties viable, we will continue to have issues with the right wing getting undue influence in our politics.

Vote with your heart, but make sure that you're okay with another Trump presidency of you decide not to vote for Biden.

Keep in mind as you do so that more than one state had enough votes for Jill Stein that if they had gone to Hillary, Trump never would have become president.

We should have viable parties outside of the two not great to horrible parties we have now. But that's simply not the way our government works as it stands now.

Last thing: you've become a single issue voter. This is the lefty equivalent of only caring about abortion and ignoring literally everything else. Politics is complicated, and I personally find single issue voters incredibly shortsighted and lazy.

One of those two will be president no matter what you do. They will then be in a position capable of inflicting great damage. Trump will use that position to hurt more people than Biden. The math here isn't complicated, and it continually astounds me how many people on the left cannot actually solve the trolly problem when faced with it for real. It really shows which people are engaged in politics as a means to an end rather than as personal expression or a hobby.
