it has been suggested that those who desire some insulation from the anti-protestors march in the middle of the column while those who are feel they are willing to dealing with angry people march on the edges.

That's a good, practical suggestion -- and it's not that I am afraid of arrest, hecklers, etc., I'm mainly concerned that raising the level of contention in society will prove to be counterproductive.

Hmm, I've also noticed that form replies from Senators have been very slow in coming.

At this point I do plan to continue participating in rallies, because I can't think of an effective alternative. I do wish there were more effective forums for discussion than internet bulletin boards.
