It used to be quite far left, back when tankies were everywhere. Now it's pretty tame, though you'll still run into literal socialists/communists from time to time. It's about where Reddit was when I left, so par for the course.
I consider myself libertarian, and it's honestly not bad, and I like ragging on conservatives anyway.
You can tell Hexbear is super communist by how much they simp for Putin, an unashamed oligarch who's so reactionary he gives Desantis wet dreams. The Lemmy instance where horseshoe theory has been hammered into a circle.
