The implied "Second Amendment Solution" threat of "I will find a way to make you regret it" is that Raymond the angry gun nut would shoot Perens, but Raymond's plausible denial after the fact was that he actually only meant he would make Perens regret it by attacking his reputation in public.

He must feel inspired and vindicated by Trump's antics.

I'm still waiting for you to mansplain how Raymond was justified in accusing members of the open source software community of being "fools" and "thugs", and how "thugs" had absolutely nothing to do with the racial context of "Blacks are Lazy".
