Here's an interesting question:

How many people were heavily offended by the words of the rabble-rouser in question?
How many amongst those answering "yes" also go on innane rants about how PC is destroying the country?

Answer these questions to yourselves honestly. Could tell you something interesting.

I think the point the guy is making is that we tend to have a kind of PC around our troops... He used offensive language to drive the point home... same way that some people who pride themselves on being "anti-PC" do with everything else.

How's it any different here?
The guy has the right to be a jack-ass... and maybe hidden in this crap there is a point about how our culture sees men in uniform.
