You seem to misunderstand the issue with US democracy.
You have that dumb “winner takes all” system where not voting effectively is the same as voting for Trump, and voting for a third party is effectively the same as voting for Trump. You either vote Biden, or you want trump to win, it’s that simple.
Hate Biden all you want, I’m sure there are better options. The point is that right now, you, me, the rest of the world, nobody has the luxury of voting for that other option. We do y want Trump, so we vote Biden. Not because we want to but because there is no other choice.
Once Biden is in, complain all you want, protest, whatever. But right now, vote Biden.
