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.
If anything it proves that if you are white and good looking, you can get into political function. I also think that with the Kennedy Assassination's 46 anniversary that occurred a few days ago, you would think these people would learn their lessons.
