It's fine to think people who disagree with you don't get it. I'm 100% sure many people reading the complaints about a female lead taking over BP feel they don't get it.
Bottom line is no one needs to get it, because it's not a democracy. We don't get a vote. Coogler makes the movie he feels he should make regardless of whether certain people get what he's doing or not, and all we get to do is vote with our dollars after the fact.
