Two days before the January 6, 2021 insurrection, there were already clear and documented warning signs that violence was likely. Intelligence units within the FBI and DHS were aware of this chatter, and the FBI’s Norfolk office even issued a report on Jan 5 warning of extremists preparing for “war” at the Capitol. Social media and fringe platforms (Parler, TheDonald.win, Gab, Telegram, etc.) were full of posts openly discussing storming the Capitol, bringing weapons, and even targeting lawmakers.
We can conclude with very high certainty that joining this clamour with promises to send busloads of people to fight was a call for violence at the time.

Even taking your claims for granted (none of this sounds familiar to me) there is no reason to suppose Kirk would have had any knowledge of it. For that matter, the FBI and DHS believing something about an ideological group doesn't make it true.
