Hard to tell from that vid, but yeah, seemed like the BJJ guy was the one being an arse and continuing the fight when they didn't have to. Much more important than BJJ in that situation would be stuff like verbal de-escalation and general diplomacy skills. BUT no idea what the context was.

Had the opponent had a tiny wrestling/size advantage or the opponent's friend been more aggressive, this could've had a MUCH different outcome. Wrestling-Judo-Muay Thai (or just MMA) is such a better base for self defense than (most styles of-) BJJ, does anyone still believe otherwise these days?
