I don't think anyone exercising a modicum of self restraint here should be worried. Free speech is an accepted given. Unless we get a bit too carried away after the 3rd or 5th vino. In which case the edit button used surepticiosly the next day could be a good option. Fear and complacency are the enemy, not the collective power of people who care about right and wrong. And we do have power, even if sometimes it feels like we don't.
We do not live under a Stalin or nazi regime. And we are not living in north Korea . With common sense express what you want to say. If people living in Tunisia, Egypt and Syria can have the courage of their convictions then surely we can as well. Remember "Time" magazine person of the year is us.
