Bad idea rewatching Utena in the middle of Penguindrum, unless you’re thinking of dropping Penguindrum
As to this fascism and post-modernism issue, it seems to me that to the extent that the Nazis tried desperately to hold onto a myth of German superiority, they were the antithesis of post-modernism and superflat worldviews etc. However, yes, I think the desperation you saw in some of these Germans betrayed a creeping awareness that not even the Germans escaped from this annihilation of absolute values (especially not the Germans). So that in a twisted sense post-modernism can be said to descend from the fascist project even though it opposes it. Put another way, if a German wakes up one day in 1945 and realizes all of a sudden that his race has no absolute claim to anything, then the only thing that’s left to him/her is to accept that no other race has any absolute claim to anything. And of course, we might dislike the way this realization plays out, but that doesn’t affect in any way its truth value.
