That does seem to be somewhat weird, although I do understand some of the sentiments behind it. However, I must admit that I find the idea of spraying Prozac and/or Zoloft into a massive crowd fairly amusing... maybe as a "time-elapse" sort of thing. Not terribly effective, though.
I wouldn't mind seeing some of these leftists exercise their Right to Remain Silent. Just in case any of you leftists missed it, the people of Iraq ARE being liberated. Why does that piss you off so much?
