Well, nudity is very natural and all. . but rightly or wrongly, I ceratinly don't want to see some hippie's tagder either when I visit Avebury.
This guy wasn't being being 'free' or 'at one with nature' - I reckon he was being a prize twat.
I'm going to shut up on this, as it's been discussed to the n'th degree forever. But I have to say, whatever you think of someone's nudity, or the naked form in general, that's you imposing yourself onto them, not vice-versa, unless of course they are persistently jumping up and down in front of you to get a reaction?
Onwards and buttwads! I think Christians are twats but I won't demand they get nekkid ;-)
