Seriously, the watershed does nothing to "protect" children (most of whom have the most open-minded, flexible and resilient attitudes until they get "educated"). At best, it allows their over-protective parents to kid themselves into thinking they are being "good" parents. Mainly to brag about it with other "good" parents at the school gates - in a python-esque we were so poor ,,, sketch way, except now it's about intolerance. It's certainly not for the long-term benefits of their charges, themselves.
As for being offended by programmes content. Isn't that the sole reason so many people watch? To pretend to be shocked by the sorts of language, undress (and activities) you'd see every day if you walked through a town on the way to the beach.
You get the sneaking feeling that some people lead such dull and disconnected lives, that they don't feel alive unless there's been something "stimulating" on the box, for them to get worked up and subsequently complain about.
