This might surprise you as a multiculturalist, but I don't think all cultures, or all facets of culture are equal.
If it was actually true that all cultures were equal then our own would be equal to its previous and future selves. If that was true there would be no point in equal rights, suffragettes, removing slavery as our culture would be just as equal now as then.
No need for new songs, food, art, science, engineering it's all equal...
