What does everyone think? Is it a good thing, or a waste of time?
Personally I think it's a waste of time. I don't think we should be BANNING people from showing their displeasure with the Government or this country. We may not like it but the freedoms that flag represents are to make statements like that. Personally I look down with disgust at any american who would desecrate the flag in any way. Be it letting it droop unceremonious, leave it fly and tatter hanging from your car etc... But just like, "I disapprove of what you say, but I will defend to the death your right to say it." I have to defend that right.
Secondly, if you agree with the ban on flag desecration, should it be implemented retroactively?

See, I can be bi-partisan.
