Sooo tough. I have hella book and activity recs for that if they’re helpful. I work in youth development and run body image workshops for Jewish kids.
I’ve heard that too re science BUT I also think that as someone who’s studied Sociology fairly extensively, there’s just no way on earth to prove what other non western cultures thought beautiful pre colonization. Besides, cultural beauty standards have generally been considered more important than genetic traits..which is not bad cuz those can be changed.
