Yeah I think you get my point. I was mostly objecting to the strict equivalence they were claiming. Across cultures you will find some relative constants in human behavior. For example, Most people love their children no matter where you go, but even that can mean different things depending on the norms and that culture.

I would push back a little bit on the idea that these differences are purely superficial. Humans can have real cultural differences regarding where they find meaning in life, how they relate to others in society, and if they ever find satisfaction, happiness, and fulfillment in their own lives.

Just because such differences can not be summed and weighed against each other to determine which culture is "better", does not mean they are the same.

This is the post-modern sentiment that I reject. E.G the differences can not be compared so therefore they are the same.
