I wonder if it is because they can sense that I will break their jaw if they do?
Stalin said something to the effect of...."in government, nothing happens by accident" (paraphrasing).
So, while I think that some of the folks are off the deep end, I also know (based on personal experience) that our current rulers are into things that would shock the average American down to the core of his/her being.
...And by the way, you're always welcome to try and break my jaw.
