There are 3 types of people who saw Black Panther (and some are combos of another):
Those who read comics.
Black people.
Casual fans who knew it was a "must-see" prior to Infinity War.
You can play, or be, ignorant about the announcements regarding Phase 4. WandaVision? Love and Thunder? The entire premises undo some of the important actions/stories of the Infinity Saga. Shang-Chi might actually correct The Mandarin, despite being a sideshow character.
Aaaaaaaaaand with your racist assertions you prove that you have, well, nothing to prove. And the conversation ends because you're so blind to facts and MCU-biased that no one can have a discussion in good faith with you.
