Personally I lean toward Pantheism, but I don’t see Trinitarian or Arian teachings as something to “hate”. They are both theologies, both interesting in their own way… why get into a huff about it? What I find distasteful is dogmatism. We are finite…why are we claiming to know so much about the Infinite?
Of course, in Watchtower world, the Trinity for some reason seems to be doctrinal enemy #1. Usually the Watchtower caricature of the Trinity is really Modalism, something that Tertullian was arguing against when he formulated Trinitarian doctrine in his work Against Praxis. I do believe that the writer of John taught something akin to this, whereas the writers of other gospels had different views.
