They agree because they don't understand what really happened.  They just heard press reports that Cindy Sheehan was arrested for protesting.  They didn't get details about it just being a T-shirt or that she didn't cause any disruption.
Ironically, has Cindy worn a nice business outfit she could have stoof up in the middle of the speech and started yelling at the top of her lungs.  

This is the "liberal" media screwing up yet again.  Oh and you probably won't hear about the Republican who was thrown out for wearing a support our troops T-Shirt.  That won't get covered at all because it doesn't fit the "wacky liberal protester" meme.  

Cindy, by the way, I read what happened and I wanted to ask you, how the sergeant reacted to you when you told him about your son?  I mean on here, the majority of us sympathize with and support you, but I'm curious as to what reaction you get from random guy who served in Iraq.
