That's some pretty weird, extreme schit. The guy had an unnatural hatred for the military like I've rarely seen, and not much common sense to boot. If you broadcast a website espousing the the death of any group of several million people in this country, I would think that your life span woould be short.
I don't advocate anyone being killed for exercising their 1st amendment rights, no matter how offensive or odious, but this guy ain't gonna have a national holiday in his honor.
