Raja -- we have people (not just in our group, but the several dozen in Mass and New England), and we have good sense, and we have resources. I'm very much in favor of your idea, and I rather think something could come of it if someone were to commit to making it happen. Would you like to propose a date and location, and we can see who else would like to be part of planning it?
I for one would be willing to endorse such a demonstration (as against a protest) in my official capacity as State Director for American Atheists. I have to suppose any number of local clergy would be willing to add their voices and support to such a message as well.
