if they don't want to be disturbed fine. But why shouldn't we go and introduce are selfs taking proper precautions. They might not know about the outside world. I still don't understand why all the hatred for going and exploring.

try to imagine thousands of dirty rude immigrants coming over and decimating your homeland. Poking their nose into your stuff, photographing you, leaving mess everywhere...no respect for custom and tradition...basically just wanting to exploit you for as much as they can get.
