There’s a fine line between celebrating the history of your ancestors and performative cultural appropriation. Being interested in ones ancestors is one thing - swearing that you’re ‘fiery’ because of your Irish ancestry when you’re 3 or 4 generations removed from that ancestry is a bit weird at best.

I think the US does have a culture all its own - some of the world’s best authors, musicians, artists etc are from the US. It does puzzle me that some US folks are so desperate to claim deep cultural ties when they have a pretty good culture already, formed in part from those ancestors.
