My dear Rat, I did not propose throwing blood on them, though it might get their attention; and they are murderers, millions of times over. I am thinking in terms of boycotting their presentations and the advertisers who support them, and exposing their lies in every possible forum. In particular, I believe we should bring every pressure to bear on the various authorities to repeal the "protesters'" de facto license to violate the law and abuse their fellow citizens. This means no more PC enforcement, the same penalties that you and I would receive for vandalism, assault, and blocking streets. Where appropriate, we should press Congress to investigate antiwar groups like ANSWER and foreign influence over media outlets, as well as the disemination of propaganda and the suppression of free speech in the academic community.
Your idea has merit, just one little hitch; we have the courts like the SF 9th to deal with and they don't want to offend.
