Michelle Malkin has some video of the war protesters in Washington, DC. As you might expect, the language is coarse and vulgar. America, of course, is a fascist society. That's why all of these people will disappear into the federal gulag or be executed without trial before the week is over. (Oh, they won't?)
My father opposed the Vietnam War--and at a time when it wasn't a particularly popular stand. (He also seemed to think quite a lot of Ayn Rand, at a time when no one had even heard of her.) But I also recall that he thought the antiwar protesters were doing their cause great harm because of their countercultural baggage. In the case of the current crop of antiwar protesters--maybe that's a good thing.
As the saying goes, "Never offend with style when you can offend with substance."
