Best argument for banning flag burning?

I went looking for good arguments for banning flag burning. The argument is mostly that people really care about it as a symbol for them.

But the more people really, really, really care about this thing that is so symbolic, the more clear it becomes that burning it is a symbolic act of speech communicating something.

1) is anti flag burning one of the worst cases of special pleading?

2) what is the best argument you can come up with for banning flag burning?
