And before being born you choose your culture? How is this different from the idea of pride in one’s race or place of birth? These are all aspects of our beings we don’t have any agency upon so being proud of such kind of aspects concerning ourselves makes absolutely no sense at all.
One can be proud of what he has directly done himself or herself, being proud of something someone else did has the same logic as enjoying a lunch someone else ate.
Heritage is a scam exactly like race, nationality, religion and all other made up concepts used to divide and conquer poor, uneducated and insecure people
