Everybody please go vote! That said, I just don't think it is nihilism.

Some of it is accelerationism - the idea that the worse the ruling class treat people they closer society gets to a revolution that will improve things drastically more than voting for dems would. I think that's flawed, but it's not nihilism.

A lot of it is propaganda. Oligarchs on both sides of the bering straight have been ploughing cash into amplifying any messaging that will depress left turnout. This isn't nihilism, it works because people believe things - we are social primates and conforming with a group is essential for our survival.

And a small amount is people who have legitimate emotional reasons, like relatives killed in israel's genocide. Not voting doesn't help that situation, but that emotional reality is not nihilism.
