You've conflated fascists with the anti-DEI movement. NASA employees are still free to live together, work together, free to vote, free to say what they please and go to their own churches.
I don't think you're pulling the wool over anyones eyes but nice try anyway. If you really do believe this, then perhaps you should read up on how fascism works. You know the whole "first they came for X and I did nothing"? That's what that's about.
I suppose hiding the contributions of minorities would make it easier to argue that they're free-loaders, non-contributors, etc. if someone wanted to scapegoat them for societal ills.
