And we shouldn't allow this concept to go unchallenged here on Lemmy.
Commenting on an active post is not brigading
Posting a link to something is not brigading
Commenting on something you were linked to 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 
In retrospect, it's funny how the liberals on lemmy.ml were haughtily saying "This may have been a tankie space once, but we will overwhelm them eventually and make it clear that they aren't welcome here" and then Hexbear comes in and they shit themselves.
they thought the reddit wave would be bigger but it turns out redditors like feeling smug more than actually leaving the corporate walled garden. so they aren't thaaat big and a good % of those who did come here are at least vaguely leftist. That plus hexbear=no more unchallenged "ebil seeseepee" type circlejerks
we have literally spent hours talking about thought terminating cliches, ready to fight them
