Enter the "Free Speech Zone" -- Boston.com has a message board up for venting over the proposed "protest zone" outside the Fleet Center for next week's DNC.  There's already a federal lawsuit filed over the 8-foot chain link fence and plastic netting around the area, which would seem to put the protests out of "sight and hearing" of the delegates, that standard having been established after the L.A. convention/debacle in 2000.  There's an interesting range of responses, from die-hard First Amendment defenders to those of the "Why don't they just sit at home and complain like the rest of us?" school.
