Don’t frame the “conflict” where one side unilaterally decided it was entitled to the other’s land, chased off hundreds of thousands of people from their homes, built settlements in their place, routinely bombing remaining indigenous populations and operating a brutal miltary occupation where said indigenous population are second class citizens with no autonomy in their own land, as some kind of even handed conflict. It’s genocide. The fact that you could come up with a justification for supporting your government in assissting this genocide is repulsive. It doesn’t matter that withholding your vote is indirectly supporting Trump, giving your vote to Biden is directly supporting genocide, which is a much larger issue than the political differences between 2 people that more or less believe the same thing but have parties that point them in slightly different directions. Trump or no Trump, you’ll still get fascism, you’ll still not have abortion access in a ton of states, you’ll still have crumbling bridges, exploited migrant workers whose kids are being separated in concentration camps at the border, trans people being denied healthcare, and leftists being arrested explicitly on political grounds.

If you want to make the world a better place you’d do a hell of a lot better to not vote at all, and spend the time volunteering.
