I did a reverse image search and I mostly got Facebook results. My wild hunch is that it's a fairly obscure image. And I assume the tedious blue wave, anti-Trump meme loving Bluesky poster saw it there and was so clueless they didn't realize it's pro-Trump.

Assume its riffing on the concentration camp in Florida being dubbed alligator Alcatraz.

i feel like most of what is popular here i'm missing the point of but everyone else seems to be in on
