In post-apocalyptic fiction, the thing that destroyed the world often looms over the ruins. It builds its armies and makes its plans, and in time, it will flow forth again and purge what’s left of humanity.
In post-apocalyptic fiction, there’s often a faction who’re trying to grab as much power as they can within the ruined world. They’re selfish and cruel, but they frame themselves as pragmatists, trying to at least protect themselves even if they can’t help anyone else. At best, they’re completely oblivious that the world’s destroyer is coming back. At worst, they falsely think they will be spared if they prove useful. Either way, all they do is get in the way of the people who’re actually trying to stop the threat.
I propose that if the queer community sometimes looks like a nuke hit it, it’s because TERFs and ace exclusionists are post-apocalyptic power-grabbers, and the looming force they’re completely inequipped to deal with is Christian fundamentalism.
