Where is Civility?

What the hell has happened to this country? Not only has common sense fallen by the wayside but civility has met its demise and we are all the worse for it.. Children in Middle School tell their teacher to "F___ off" without fear of reprimand, members of Congress shout insults to each other like kids on a playground and grown up(?)people throw bricks through the windows of those with whom they disagree! there is a vast difference between freedom of speech and hate mongering and incitement to violence.
