The only thing Black Panther gave SJWs is Wakanda memes. The whole message of the movie, that the protagonist repeats over and over, is that black people are not his people. His people are his people. And in the end he doesn't just employ his nation's resources to help black people, he makes a point that he's trying to help the world.
Yes, SJWs are masters of completely missing the point, but I have a feeling the ones deliberately trying to steer the mob don't want to have to deal with possibly sullying such a "woke" movie.
