Left wing accelerationism as pictured by Snircek and Williams in their work is missing a lot. It just references women's issues, minorities' issues and colonial issues but doesn't really incorporate or develop ideas on how to integrate solutions to these problems in an accelerationist, pro-technology, anti-natural perspective.
So there are a bunch of authors and collectives working to enrich, directly or indirectly, this ideological framework to make it more encompassing of different human problems. Xenofeminism is one of them but it's also a lot more than that. While there is a certain dialogue between xenofeminism and the accel world, they don't really pose themselves as "we like these two guys, let's add something to their work" but more as an indipendent field of research and an indipendent methodology.
Xenoaccelerationism is what sits at the conjunction of these two positions, that while similar, can still exist without the other. But to me, it's pointless to abolish work under accelerationism if we cannot abolish gender under xenofeminism. It's pointless to talk about technology repurposing under accelerationism without talking about technology dissemination and hacking under xenofeminism. It's pointless to fight bio-capitalism under accelerationism without fighting the structures that allow it under xenofeminism.
