Just to add to this "get kids interested in history" argument. I think the "diversity"-spiel is a chimera. No real follow ups are usually done on how it might achieve said goals, on the contrary.
I feel it's more of a PR-opportunity for companies, government authorities and also in our case, the Swedish Defence Forces.
Again, it's a sign of the times. Kids want to hear this stuff to feel good, but I doubt it actually matters when it comes to actually garner real interest past that.
