Oh, for crying out loud.
The whole point of America is that you can burn the flag. Nothing sums up her greatness so succinctly. And it is precisely this – that in America you should be free to do any damn thing you please so long as it does not impinge on the rights of others – that leads most of us to abhor the idea of burning it in the first place.
And one thing you should absolutely be free to do in America is criticize your country and express outrage at its behavior – even if you’re wrong. We call that the Bill of Rights.
