I think the word "accelerationist" has the potential to become the next "tankie", or even a worse, more mainstream version of it. In the way a small number of liberals are currently using it, it is equally useless for understanding the world / equally useful for misunderstanding the world. It can be used to equate any leftist with a person who wants to start WW3. It can be used to draw a connection between the far right and the far left, without even having to use another concept like "authoritarianism" to mediate the comparison.
We are also quickly approaching the part of the American electoral cycle where liberals will start trying to suppress any non-abstract criticism of the Democrats. "Bernie bro" will start to seem outdated, so they are in need of a new rhetorical tool.
"Tankie" could also serve as this tool, but it has the downsides of its meaning being harder to intuit from the word itself, and its explanation including an actual historical event. "Accelerationist" is also directly rhetorically related to the current campaign of hate towards LGBT people, but does not necessarily reference it so it can still be used by cis people to insult trans leftists.
I actually agree with this one. Since libs thing voting for the blue racist is harm reduction, they also think that by not doing that you're intentionally trying to make America worse. And if you start talking about how voting blue vs voting green or whatever other color you wanna vote do basically the same thing anyway they'll start going off about how you're just mad and trying to destroy the world over it.
Meanwhile I would argue that voting blue no matter who actually is an accelerationist act but libs won't understand what that word actually means so
Also, not voting at all
