What can I say? This little episode caused one person to lose his temper and start throwing out insults, God knows we don't need to set off part II but personally as I've said I think it appears to be on the face of it a derogative term, 'Nut-Job' in a similar vein to 'Spazzo' or 'Retard' which aren't usually considered satisfactory to use here. Certainly I think he had mental problems which I can well imagine leading him to do what he did, maybe he was so affected by what he saw during the protest, maybe having recently attempted suicide he did not care what happened to him, and maybe we'll never know. It certainly kicked off a tragedy for another and their family and friends and injury for one more. I'm just of the opinion that the loss of life was a tragedy and they had people who cared for them.
Me adding 'He was abused as a child' was merely me adding to the history you were posting about as a by the by, something quite typical in his background but none of it relevant to his death, however my comment was seen as something else, best let sleeping dogs lie.
There's not much that I really understand about American Gun Culture,, as a British person we can have our opinions but getting our heads round it isn't simple. I think if we tried to relate the protest and attendance of the Militia's, their callout for individuals to come and bolster their numbers then I would think of the protests and riot in Croydon, Surrey (South London) a few years ago now and as a place that I worked in during the 80s and 90s an area I knew and was familiar with, a family owned business of decades burned down just around the corner from where I worked, and I can't imagine any authoritative body apart from the Police, or the Fire Brigade and Paramedics having legitimacy to respond, the vast percentage of the police wouldn't bear firearms, we certainly don't have militias in the UK and if we did it might mostly be farmers with shotguns and pitchforks they could maybe call upon, it might take several days for them to arrive driving tractors.
I'm afraid all that comes to mind having groups with their own agendas calling armed individuals to join them under what authority's tactics and control (?) is just insanity.
