QFT. This is all that needs to be said. People are taking the question to mean more than its not.
If we're gonna get REALLY REAL...I'm only black because white people tell me I'm black. If I go anywhere on earth....I'm a man. Im really only a "black man" when I'm around white people. When I'm in my house...my mom see's me as her SON...not her BLACK SON. White people didnt come around until 10 thousand years ago...before that there were still MEN and WOMEN.
Race is just a social construct. You can remove my skin from my body....and I'm still a man. You can cut my dikk and balls off and I'm still a man.
The only reason you say "black female" is because you speak english and "female black" isnt grammatically correct. If you spoke spanish you would say "mujer negro" your point isnt valid because its just dependent on language.
The question wasnt "which march would you go to first" tho its what do you identify with first.
I dont even think this is a question...like it doesnt even seem as if people have an option in this case. Biologically I think we're humans first, then our sex second and thats just fact.

Being whatever sex you are is so visceral to yourself as a person, people dont even question it. But they question race all the time.
Let me ask some of you this....would it be easier to imagine YOURSELF as a white man...or a black woman? Would it be easier to imagine yourself...the exact same person you are except with lighter skin, a better job, and less athletic ability....or to imagine yourself with the same skin tone except giving birth, and having to ride a dikk, and lacking any semblance of logic? Which one is easier?
