Looks like they hope to create a confrontation with reagners and paras in order to boost their publicity. we suggest that Freepers march in with them carrying signs that distract their message, such as "Eat at Joe's (or some other local eatery)" and, my favorite that I saw on a Tee-shirt in Cambridge with a beautiful portrait of a cat: {I love cats -- they taste just like chicken." What I think should be tried is a new tactic when hard core lefties have few numbers and are desparate to boost their stock through feee media: confuse and disrupt their puny message so that the idiots of the lamestream can't make heads or tails of it.
While that may be a style some folks would follow, I prefer to stay separate and apart from them.
They are an agry bunch - for peaceniks - and moving about within their ranks like you suggested is just asking for trouble, and bad press.
Our message is a good one, and if we disrupted their rally from within, and scuffled with them, the media would play it against us.
It's always better that we stay separate - better for the media and general public to compare and contrast our two sides. 'Least that's my opinion.
