This has become so non-stop that I had to do some research on logical fallacies because I was quite sure that there was a formal name for what we're seeing from anti-electoralists and accelerationists (the Venn diagram is pretty much a circle). And I was right.

In this thread there's actually two (at least).

• False Dilemma (aka false dichotomy): "You can either support genocide by voting for Biden (or Trump) or oppose it by voting third-party (or not voting)." This is just ridiculous levels of oversimplification with an implicit nested False Equivalency fallacy ("both sides are the same").

• Denying the Correlative (what I had to look up): "Vote third-party." In the first-past-the-post, two-party system, there are only two choices that can have an impact. According to the data, voting third-party is nothing but a spoiler for the candidate of the major parties that one prefers. The choice is Biden ⊕ Trump. This fallacy is basically the inverse of the False Dilemma, which makes it all the more impressive to see the two used alongside one another.
