Then why should the diversity of the Amazons stop with their gods?
The Amazons we meet in Wonder Woman aren't the Amazons as the Greek presented them, so why should the Amazon gods be the same as the Greek presented them?
(Not that DC ever really has managed that, but I digress…)
So why the reaction against a black Aphrodite, then?
Also, remember that the "modern" depiction of the Valkyries was a very recent invention during the Viking era.
