Well, I gotta say the guy wasn't too bright to walk into the middle of an angry demonstration and disagree. Looks to me like he was lookin' for trouble.
It also appears to me that the demonstration was located in an area much nearer to the so-called Ground Zero. Wouldn't you think it would be at the proposed "mosque" site? Of course, if the demonstration were at the actual site of the proposed Islamic Cultural Center, people would see how insignificant the site is - and how nice it would be to have some new construction instead of abandoned buildings on that space.
