[nautilius]

‘Be careful how to express yourself’ is needlessly conspicuous. Never in my life have I seen anyone hold back to criticize politicians or people in power, most certainly not in some cab.

As I wrote somewhere else, if you think the first amendment gives you the possibility to say what you want to whom you want, without any consequences, go to the nearest policeman, start insulting him and his family. I am sure there will not be a problem, and he’ll sit through it for hours, if you just make clear you’re exercising your first amendment rights.
