I don't think white people are all from the same place.
I don't think you'll find anyone taking issue with Italian pride, or Irish pride, or Greek pride, or Norwegian Pride. Those are all different countries with drastically different heritages to be proud of.
such a weird comment
I don't even really know what it means? black people from Greece can't celebrate black pride?
My point is "white" isn't a culture or a heritage. It's a color.
Honestly, same holds true for "black", it's just a color. In our country it is synonymous for "African American" and if people want to have pride in their shared experience of being stolen from their homeland, enslaved, overcoming that, overcoming racist things like Jim Crow, etc... cool IMO.
Likewise, if people want to be proud of being descended from early settlers here who established the colonies, no one is going to get on their case for doing so. If they want to visit Jamestown to see what it was like for their ancestors, or Plymouth Rock, they can. If you're white and your ancestors came here through Ellis Island, you can go visit there and be proud of them surviving the journey here and establishing a new life that led to you. All of these places are national parks and exist just to celebrate these things.
There is no one single unifying story for the masses of white people who live here, there are lots of little stories. Maybe your family came here due to the Irish potato famine. Maybe they got a land grant from the King of England.
Maybe they won tickets on the Titanic in a poker game. Could be practically anything. Unfortunately for people who are "black", the vast majority ended up in the US under the similar experiences, slavery. So, for them celebrating their history and finding pride in it is a joint exercise. It would be pretty off base for a Black Greek who came here a couple years ago to involve themselves in the black pride stuff, and they most likely wouldn't want to, they'd rather go to a big street festival for Greek Easter or something that was more similar to their own experiences.
