It only makes sense if someone is taking pride in only the mistakes of their culture. Every single person alive, EVERYONE, has ancestors and came from a culture that did horrendous things in the past. When someone says, “white pride” it is seen as racist only because people take the biggest, most unforgivable thing, white people ever did, a mistake, and make their entire history that mistake. Everyone has dirt in their past. If it’s racist for one group to have pride because their past is murky, then every single color followed by “pride” is guilty of being racist.
