And what about the "Hey, fascist! Catch!" one?

It comes across to me like you're ignoring a plain reading of the evidence in favour of one that refers to an even more cryptic group. (There are also other comments in the discussion arguing that this group disdains political violence.)

The full etching was ""Hey fascist! Catch! ^ > vvv" (an up arrow, a right arrow, and three down arrows). This is a Helldivers 2 input for calling in an "Eagle 500kg Bomb."

The plain evidence is that each etching is a reference to an extremely online/gamer meme, not leftist slogans.

> The Terminids Icon Terminids, sometimes referred to as the Terminid Horde[1] or Terminid Swarm, and commonly called Bugs, are one of the enemy factions in the Second Galactic War. They have control over 21 planets. The Terminids have been identified as "Fascist"[2] by Super Earth Icon Super Earth, despite the individual Terminid clearly being incapable of comprehending the ideology.

But you're missing my point, which is that it's too early to speculate. Pundits were blaming trans people and leftists before the bullets were even found.
