And we shouldn't allow this concept to go unchallenged here on Lemmy.

The only thing that might be brigading, but isn't because it isn't a real thing, is someone explicitly going, "Hey everyone, go here and harass this person"
It's all fine and good that we have some new rules to keep the peace with other instances but we must fight against 
It seems to me that instance has a very evident and festering
problem, which is incredibly strange for what is supposed to be a pro-trans instance.
They're being tone policed down to
levels, but they're still spreading the same hateful talking points that prevents the free expression that the admin team supposedly desires.
This is my first time seeing it first hand but it's so obvious and transparent that their liberal well intentioned inclusiveness has already backfired horrifically. When hexbear users confront these tone-adjusted fascists and question their hateful anti-left stance (something the mods and admin team should be doing but lack the spine) they cry and demand defed because their views absolutely can not stand up to any sort of serious analysis.
I will say I would not have seen this without federation. It genuinely makes me appreciate the amazing community thats been cultivated here because it's not easy to challenge, and remove, a polite abuser standing next to you.
If anyone is communicating with their admin team, I think they should be told to wake up because it will only get worse before their community is co-opted and they're the ones being "tolerated." I am being constantly reminded of this https://youtu.be/P55t6eryY3g?t=677
The fact that calling it out plays in to the fascists hands is pretty depressing too.
