I hardly started any drift away from discussing this dodgy character and his ideas.

The fact that someone is has a distinguished career in the military is hardly a safe indication that they are trustworthy members of a democratic society. Goering comes to mind, and I am sure there are lots of American examples.

I suppose the question is, how do you best deal with this kind of incitement. In principle I imagine there might be something in your all embracing Patriot Act which could be brought to bear, but I doubt if that'd really be likely to help.

Maybe the good guys could move to Wyoming first instead.
