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.
Except the majority didn't put those people in power when we're talking about Texas. Texas is not majority Republican. Most of the Democrats are concentrated in the urban areas - Dallas/FW, Houston, Austin, etc. Nevertheless, there's a nearly 50/50 split in population affiliation. However, the Republicans control the state through a combination of voter suppression and gerrymandering. And, of course, the independent wildcards.
Point is, it's not the majority who are keeping the state red. It's the majority of the people who are allowed to vote when calculated in such a way as to make Republican votes count more than Democratic votes. The state is rigged to keep Republican control regardless of the actual majority.
