Could be, but you know our history regarding adopting other's culture and claiming it as ours...
Silly NG! Every culture has assimilated other cultures from before, during and around it in order to make its unique mix.
Current opinion on the subject is astonishingly limited to seeing the spectrum of time based only on the last few hundred years.
500 years from now, if US exists, people will finally acknowledge a legitimate US "culture". but we got it from elsewhere, of course.
500 years after 500 years before the US colonized north america, people are making the opposite mistake. Seeing the most recently developing cultures as illegitimate, while seeing the older cultures (who are about equally a mixture of taking and mixing) as legitimate.
Same thing I say about climate change. If only we knew where we were on the spectrum or in the cycles........we could speak more authoritatively.
But I find no excuse for failing to understand we ARE
somewhere on that spectrum. It exists, and the bigger we fail to measure the whole spectrum, the more off-base our conclusions will be. (said in general, not to you NG).
The only cultures that have a bit more claim to cultural legitimacy are the first ones to ever exist.
