You’re … not wrong.
But, I don’t think these will be used for historical wargaming by enthusiasts (or if they are, the provenance Will Be Known, and either go unremarked/understood for what it is or otherwise accepted for what it is regardless). As in many other things, representation matters, and the fact is, the modern military has women in it.
Kids may not appreciate that these toys emerged from a specific era, but they are the audience, and will bring their own ideas and imaginations into play.
Jingoism is a reasonable concern, but the responsibility is still in adult hands.
Just like toy cars and airplanes: the act of playing with those toys doesn’t meaningfully influence the current extinction and climate crisis—they’re just toys.
Sorry for the downer. I think these are nice toys, and the sentiment is worthy of a little recognition.
