Have you had a bad experience with punctuation? Did a semi-colon bully you? Maybe you feel exclamation points are too aggressive...
I will try to help you appear more learned even though you have resisted so far..an intelligent man does not have to refer to things he doesn't understand as "stupid". On the contrary, an intelligent person finds the things he doesn't understand as an opportunity to expand his knowledge and dives into the challenge! Is it the hyphen or the designation you object to? I don't understand the fear inspired by my African appearance but I acknowledge it exists and I've studied its effects my entire life. (I want to call it stupid, but that would allow it to sneak up on me!)
Secondly, it is the height of ignorance to believe you can determine someone's nationality or cultural identity by looking at them! For example, you or someone equally enlightened used Giannis as an example of people misidentifying others as African-American. He certainly "looks" like one to me, but a little discernment and a little intelligence and you realize he isn't. He is African-Hellenic (BTW: Greeks call themselves Hellenes not Greeks)
Thirdly, African-Americans come in all shades and colors partner so "looking" at them doesn't give as much information as you might think. Wesley Snipes and Steph Curry's mother, Sonya, are both African-American even though one has short kinky black hair, dark brown eyes, a wide nose, and very dark skin-the other has long, blonde hair, blue eyes, a thin, sharp nose, and very pale skin (she was "accused" of being white by George Shinn who was angry because he thought she was a white woman dating black men!) So in your world it is ok for Snipes to identify as African-American (if he agrees to drop the hyphen I guess) but Sonya cannot because she doesn't "look" the part.
Fourthly, What exactly do I look like??? There are peeps on here I have met back in the day when we had the in-person meet/greets! I bet they would say I "look" African-American if it makes you feel better! (But I look nothing like Mr. Snipes so maybe my appearance wouldn't quite fit into your comfortable world view)
Lastly, once you get past this ridiculous obsession with what I call myself, you will be able to see that it doesn't matter in the slightest and is nothing but a distraction that keeps you from dealing with the real American problem....valuing peeps that "look" or "sound" different without condescension or condition! Fight the real battle and all win!
