I was there and helped break up the near riot. I agree, the Protest Warriors methods should only be used on the other side. Some of the guys who rushed them still didn't get it when I explained it to them.
As much as I hate to say it, most folks there were not Freepers. At least not yet. Anyway, we still have to use sarcasm tags here because folks don't get it. So, I can understand the confusion. Still, someone should have used the opportunity to explain it after it was all over. Now I will quit repeating myself and move on. (um, not as in moveon).
