I think it's the history of the word and where it derives from how it's used too cause it was probably used to degrade mixed people back in the day they weren't seen as "high"as they are today but more so mixed breeds with no sense of culture or belonging to any community really which is wrong your still human. I think people mixed especially or anyone from two different cultures in general should Identify as what they please as it can be challenging and you should just go where you fit and feel like you belong tbh that's it. You should just say i'm mixed or black since you came out a black woman lol.
Whatever makes you comfortable don't let race take over your life your a human being before any race.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
