Cursuswalker,
I don't think the issue is with Paganism. It seems to be that the anti-social behaviour of a minorit(?) are spoiling it for the serious Pagans. When I see "Pagans" at ancient sites I get the impression that there are numerous pseudo-Pagans present, almost as a trendy hippy type might. For many it'll be a phase they are going through. I don't mean this in a demeaning way towards Pagans, it's just that some of the hangers on are giving Paganism a bad name.
Regards,
TE.
