I think you may be viewing my thoughts through an uncharitable lens. I am not bothered at all when anyone celebrates any aspect of their identity.
I’m a white Australian; my ancestors committed atrocities, yet, I do not feel shame for their actions, because I wasn’t involved. I can only take shame in how I have acted.
To reiterate, the definition of pride is localised to the individual. It doesn’t make sense to be proud of someone else’s accomplishments if you haven’t helped them.
A parent may feel proud if their child has done well, they have contributed to their success. However, if my college in a different department gets a promotion, I shouldn’t.
Now extend this to people you don’t know, and it makes no sense at all.
