And we shouldn't allow this concept to go unchallenged here on Lemmy.
Commenting on an active post is not brigading

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 
So much of the 'brigading' is just comrades pointing out and challenging racism or bigotry and agreeing that a reactionary is racist or bigoted. I think its this kind of collaboration that comes off as so offensive to them sometimes; it's not something that any of us have to argue about, so it might always come off as co-ordinated to those who are used to saying whatever tf they like without consequence. Must be strange to be challenged when it's acceptable to be a a conservative or a 'progressive' and a POS throughout most of the western world.
What would it be like living in a world where anyone who dared to voice bigotry or misogyny or transphobia was immediately dogpiled by everyone around them? Like someone makes a bigoted comment in the grocery store and everyone around starts yelling at them and calling over the rest of the grocery to yell at them? Sure, witchhunts, whatever but god it would be nice living a world where if you encountered a bigot or a fascist or a cop everyone would pile in to help you without having to be asked or having to think about it.
i just want to be able to call the gender stasi when some transphobe starts shit 😔
