That’s indeed contrary and disrespectful of their original intent, but why does it matter what culture does it?

If people from a traditionally Buddhist country like Nepal disrespected Buddhist ideas, it would presumably be just as disrespectful as if people from America did, so I don’t think “cultural appropriation” is the right way to analyze this.

By the way, practically every religion has been transformed and warped so much over time as to be almost unrecognizable. This again is normal human behavior.
