parts of very old practices remain, others are lost or altered
they are like language in that way
I have some familiarity with Hopi life. Many of their ceremonies have been closed to outsiders because of obnoxious behavior. Comments like yours above would be a fairly good example. Your reaction to the privilege of observing a part of their ritual cycle derided because they collected a nominal fee to put up with your intrusion.
The fee is like someone charging a small amount to "give away" something like a puppy or kitten. It helps filter out the worst of the assholes. Jerks who are unwilling to spend even a small amount certainly aren't worth the bother. Even those who pay can still be insensitive, but at least maybe they will shut the fuck up during the event so they can "get what they paid for" instead of wandering off and snooping in places they are not welcome or talking/taking photos when asked not to. That sort of thing.
Viewing other cultures as a form of entertainment vs. observing and learning about them with respect. - the difference between a tourist and a traveler.
