Good point. The "intruder" language is mostly supposed to be bantery. I'm happy to have people that are into big government, shitcoins, or other things I disagree with at our meetups. The problem was definitely more with the anti-social behavior that made it impossible to have a discussion. I'm not sure if the reason for the anti-social behavior is relevant beyond identifying potential ways to safely mitigate it.
As far as his working for the DOD, I think the line you're makes more sense in the context I wrote it. My beef with that was his almost gleeful description of working on deadly weapons that are being used in ways that are, ironically and by his own admission, being concealed from the public. I hope that clears up what I meant there.
