Well that might very well be true for Wicca, in terms of Gardnerianism, as they are the originators of that term. So I say let it go and just call yourself a witch or pagan, as I always thought Wicca was a dumb name anyway..
I was trained in a coven of Alexandrian extraction that used a pantheon, although they would always pair up a different set for each holiday to be called down upon the priest and priestess in line with the dualistic focus of Wiccan ritual. Although in practice, much like in ATRs, other gods could begin to show during the ceremonies. Here we can start to see a progression away from the model informed by study and inspiration from the spirits.
I have to say I have always regarded the obsession with dualism, along with traditions of of being "sky-clad", and the use of the flail or flogger as a ritual implement in initiations as all having to do with Gardner's personal sexual obsessions and subsequent reactions to the post-Victorian culture in which he and the initial generation of Wiccans was raised.
