That's the great danger. We slowly start to accept more and more things, without realising it's not good. I agree that any nudity should be banned. Don't see any argument pro, see many against in the Bible... @Astrid: You're a girl. Girls have less problems with nudity (I think). Guys (or at least I) have to be very carefull with that.
Just my opinion, and I respect all yours, knowing I don't have all wisdom
