We know of at least one white vet who was clueless about black men in a war he was literally in. We’d be crazy to think people know something about history as a given. Diversity is a good idea in general… It just is.
For example I never knew there were black women behind the space launch until I saw a movie. It’s just never something I’ve been told nor assumed. Hollywood is trying and games and should too. It’s not like knowing and sharing that story suddenly takes away from other stories.
