The users at Hexbear made it perfectly clear in the discussions about federation that they weren’t going to respect that request and were openly encouraging each other to brigade other instances.

Source: trust me bro.

and a quick scan showed several comments about sending offensive DMs to users of other instances

I've looked through several Hexbear threads and I haven't seen a single indication of this. The most common sentiment I'm seeing is "fuck 'em, we're better off without them." Link me these alleged comments, please.

The idea that BH users would have been well behaved is wishful thinking as they’ve already shown the Fediverse how they behave.

Frankly lemmy.world users have shown themselves to be considerably worse, straight up making shit up and calling Hexbear users “Russian bot farms” and “a cesspool for genocidal lunatics." All the incivility is coming from the frothing-at-the-mouth libs who can't stand that other people might have genuine anti-imperialist views.

ideologically motivated extremists

"Extremists" lmao. The nerve of you calling HB a "troll army" after posting all these completely unsubstantiated lies.
