Why would men and women choosing to exercise their 2nd Amendment rights make you so uncomfortable? It seems pretty clear the militia guys were welcome there. What's the problem? Please tell me you're not one of those people that think just seeing a legal weapon in plain view is cause to tattle? Open carry IS still legal in most of the US. Chicago and DC do not count as they've clearly been ceded to communist authority. It always seems strange to me when people that claim they support the 2nd Amendment get all weak in the knees when people actually exercise that right.
I have no problem with state executives having the authority to direct their state's guard to do their bidding, provided those guardsman that respond remember the oaths they've taken, but un-elected federal alphabet agency heads should have no such authority.
This does not have much to do with the 2nd in my mind. The guns are a tool that the militias were misusing, but it could have been anything from a pitchfork to a pipe-bomb to their own kids as human shields.
As far as I'm concerned, the militia clowns are actively supporting an ongoing crime. You don't have to 'fear' a kid in order to spank his ass, and in fact it's hardly ever the case. When the kid does something wrong it's appropriate (in my opinion) to give him a spanking. Usually it's not something that the kid or the parent wants but at the end of the day, the kid is better off for it (I know I am.) The parent understands this because they have greater wisdom and world view.
The American public to the militia clowns is fairly analogous to a parent/child relationship. And if deadbeats and brats get away with doing bad, it will spawn more deadbeats and brats so the appropriate action is to put a stop to it as early as practical. Bundy is a good example. He got away with pulling his shit for two decades and here we are today with a much more significant problem than we would have if we'd thrown his ass in jail for a few days back in the early 90's.
