Personally I think Violence is a weak rationale. Technically, I guess, yeah, he said anyone who disagreed with him should be physically beaten, but that's a stretch to call that Threat of Physical Violence" from the forum that disdains SJW's definitions of Violence.
It didn't matter who the guy argued with, Pundit, Jeff, Voros or Headless, once he started arguing, the guy was 100% disingenuous Forum Warrior. There was never a point to engaging him on any topic with which you disagreed with him, including in the games forum.
The guy was a Personal Avatar of the concept of site disruption. Even devoted Pungency Warriors and Pundit Haters like Rincewind make good, non-flame posts when they feel like it. Did Biscuit make a good post ever? Anywhere?
Personally I was convinced the guy was a fake from the get go. He was just too perfectly aligned to butt heads with the Gaming and non-Gaming areas of the site, a persona created for shits and giggles to get the whole place in an uproar. For example, someone who actually held his political beliefs would have dropped a lot more names. Occasionally Rince or Voros actually send me looking to see who they are talking about, something that never happened with Biscuit since he spent all his time in Evasion and Rhetorical construct.
Anyway, Site Disruption based on posting history and argumentation style would be honest. Actually using the Violence Card seems like an action in search of a reason.
