isn’t that just “pride” in being/having been discriminated?

No. I can’t imagine there’s a single person who has ever felt legitimately proud about being discriminated against in a manner you suggest.

Proud of continuing the traditions of one’s ancestors so they aren’t permanently lost to historic racism or diluted in the modern melting pot, via artistic expression, etc, yes.

You still have plenty of time to talk to people and change your viewpoint.
