I do wish that Paizo would make a clearer distinction with the Ancestries between your ancestry/species, and the culture of your ancestry. Saying "Dwarves believe this" comes across as weird and a little racist sometimes. But saying "many Dwarven cultures value this deeply" gives you a sense of what growing up in a Dwarven household might be like, both for Dwarves and those who may grow up in Dwarven society. Otherwise, it comes across like old D&D saying "Drow are evil," "Dwarves hate Elves," "Orcs are dumb brutes," etc. which takes away some player agency. And sure, you can take it in your own direction and do as you will with the ancestries using what the book says as a guide to the general culture, but I'd really like it if the book straight up treated it as a cultural thing, and not a genetic thing. Maybe I'm reading too much into it and the term "Ancestry" is supposed to do exactly that. I dunno. But when helping players make characters, I always introduce those elements as cultural rather than ancestral.
