You can't 'steal' culture, idiots.
You can steal pieces of art, which may or may not be cultural artifacts, but the more people sharing and engaging with a culture, the stronger that culture is.
Conversely, nobody but the Indus are enjoying Indus culture right about now, which is why nobody has any fucking clue what it is.
If you just want to create petty grievances by saying "oh, I don't think white people let me do things, so I want to stop white people doing things as retaliation" just own your fucking racist idiocy.
