I don't see the issue with Cam saying he prefers to be called Black. I don't agree that all Africans have an issue with Black people, but I have been told similar things from people from different countries in Africa. That being said, ive also seen them usual 2nd generation or 1st but younger identify as Black and whatever their nationality was. I've also seen some never claim to be Black until they run into issues with white coworkers.
Personally, I prefer Black. It's not a slight against my African heritage as much as I don't know where in Africa my family is from. I also find it weird that the response is always we had a history before slavery as if we didn't have one after.
Recently, I found a Youtube channel on DC/DMV history from a Black perspective. She usually makes videos about the changes in DC neighborhoods in the last ten odd years with a focus on Black people being displaced and indirectly gentrification. Benjamin Banneker gets brought up alot as far as being an architect for DC. However, the other people who built neighborhoods who were never mentioned in Elementary or Jr high/,middle school. I can't speak to high school since I didn't attend a DC high, but it wasn't covered in the Maryland highschool either. I honestly learned alot that I never cared about from her channel in my youth and clearly wasnt tought even with primarily Black teachers. That doesn't speak to the rest of the positive things Black people have done. Everything doesn't have to be centered on slavery or discrimination. Instead of focusing on Blackwall Street being bombed, why not focus on the people who made the city great or rather what the city accomplished before being destroyed.
My point is Black or African Americans whatever you want to call yourself there is history we can be proud of and we don't need to look to Africa for greatness. I think if we took more pride in what we've accomplished here beyond entertainment, it could encourage kids or people in general to want more and do better. That doesn't mean acting as if Africa doesn't exist. It simply means learning about history and customs you can easily connect with just like our African counterparts.
