I don't think that "only old white guys could possibly have enough experience, training or other safety expertise". However, it is probably true that if you exclude that part of the labor pool that does not like your safety look, then you may end up hiring a lot of young people who don't have much experience. Needing an excuse for this, one could claim that you're just avoiding old white guys, which sounds better than avoiding workers with experience to know what a normal safety culture looks like in a submarine. As to the racial makeup of the experienced-in-a-submarine demographic, I don't know of any data on that, but I would not be surprised if it were mostly anglo.
