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 elsewhere when they have a pretty good culture already, formed in part from those ancestors.

I’m both cis and hetero. There is not one iota of evidence I’ve seen that there is any sort of movement that wishes death on cis and hetero people, or that organises vigilante groups to hunt down cis or hetero people to beat them up, or that invents bizarre rumours about ‘what they do’ or conflates cis and hetero people with paedophilia or that tries to organise campaigns to get cis or hetero-centric book removed from libraries.
There is no formal or informal system of oppression towards cis and hetero people. It just doesn’t exist.
