Banned for being a "known tankie"

I saw this post titled "Scratch a anti-harm reductionist and a fascist bleeds" (https://lemmy.world/post/33320759)

I commented that "harm reduction" apparently means sending billions in weapons to israel while they commit genocide and shutting down campus protests speaking out against that genocide. I said that seemed pretty fascist to me.

Within an instant, they downvoted my post and banned me. Guess it's my fault for posting in a circlejerk community, but I'm still scratching my head on how that makes me a tankie. Something tells me this mod would be calling in the tanks to suppress any dissent if they could.
