Lack of Respect
These people had the balls to somehow get into the RNC and attempt to disrupt Sarah Palin's history making speech. I may be wrong, but I did not see any press coverage of people trying to disrupt Biden or Obama during their speeches.
The other thing I hate about some of these groups is their lack of respect towards private property - case in point those anarchist who are protesting outside the DNC who found nothing better than to attack delegates as they got off the bus. What the hell is wrong with these people?
