There is a difference between cultural appropriation and cultural appreciation but lately it seems any expression of foreign culture all gets lumped into the former. The reality is that culture is fluid and that all cultures borrow from others. What matters is whether or not it is done in a exploitative manner. As an example tea originally came from China but now is viewed as an inherent part of British culture. The British in turn introduced tea to India where it has been readily adopted into their culture. The Chinese also introduced tea to Japan where the very elaborate tea ceremony is a defining cultural practice. The reality is that we live in a global world and culture doesn't stop at the border. I don't believe that the appreciation of a culture's food, clothing, or practices should be restricted to their own members but it should be done in a respectful manner by those of other cultures who choose to adopt them.
