I suspect it's only going to get worse - the fourth generation since WW2 (more or less) is about to enter their teens, and when something's as far back as your granparents' parents, it's ancient history and prime for twisting in new ways (not that the distance has stopped the Nazi fetishisers all these years). All they will have are second-hand stories.

I mean, why else is Steampunk with late-Victorian elements getting so big now? And in the late Victorian and Edwardian periods, it was the turn of the 18th century with the Neo-Classical and Romantic stuff. (I think. My dates might be slightly off, but I remember thinking how interesting it was when I learned about the cycles of art and stuff that it seemed to be about 3-4 generations between when something was new and when it became quaint and fetishised - right when the only people who actually lived in the original period were almost gone.)
