Please dont do it. 1A is protecting you, but they still got guys with batons, tear gas and tazers. It is not about the letter within some law but rather how it is practised, by insulting someone strong enough, law might protect you but at the end you will still finish as a begger. And, me personally, I wouldnt dare to do it in states. Actually I would rather do it in Switzerland. Or maybe even Thailand.

I disagree. This is the very thing freedom of speech protects, bar violent incitement. The great thing about the US is that FoS is not not just a law, but also a cultural tentpole. I doubt the people holding the tazers would carry out their orders in this case.
