ANYWAY, if you Do Not want to be fed misinformation to by clearly biased fans, here is what actually happened re: Bruce "bullying" Guy
The whole run has the tone of everyone being rude to each other. Everyone gets into fights. However, other members manage to keep it verbal. Notice, how Bruce isn't trying to start a physical confrontation, and instead telling Guy to cut it, and Guy is the one that escalates to physical.
Guy was fully ready to strike and had his fist charged.
But Bruce's reflexes are faster, so he strikes first. He is simply responding in kind. Also notice how literally everyone else is on Bruce side - because Guy was a nightmare to the entire rest of the team for all the previous issues. This is Not the first time he escalated to physical attacks - the literal first issue of the run starts with this:
And it continues on in the next issues too, with Guy being sexist, xenophobic towards J'onn, and just generally mean towards others, even the ones who never did anything to him - like Captain Marvel. And, yet again, Bruce is the one to step in and cull Guy's bullying.
He sullied his relationships with the entire team, and the punch above? Is written to be a cathartic moment for the readers - the moment where a bully character is finally put in his place. That's why literally everyone is on Bruce's side, including Clark and Diana.
It is also not Bruce's punch that leads to Guy's change in personality - it's him hitting his head on the table right after. He wakes up after the punch exactly as he was.
As I said above, Bruce has no such issue with the rest of the team. They are all harsh to each other, yes - but they manage to contain to verbal jabs, and Bruce has no problem apologizing to them.
So yes. Guy is the bully here, not Bruce. Even Hal isn't a fan of him at the time. So stop woobyfying him, my god, yall are worse than Tim stans
