Anthropomorphic? No, I don't believe so. We ascribe human characteristics to the gods because of what Krishna says in Bhagavad Gītā 12.5 "For those whose minds are attached to the unmanifest, the path of realization is full of tribulations. Worship of the unmanifest is exceedingly difficult for embodied beings."
Basically, the true nature of the gods is so far beyond our understanding we can only relate to them on our level. This of course, is my UPG.
An interesting perspective. I look at it in a similar fashion, though with a bit of a distinction. As I said earlier (though in somewhat different language), the way the gods are depicted in storytelling is basically for literary purposes, and that would include things like anthropomorphism. A couple ways we might spin this around a bit, though.
First, it seems we can approach the gods in ways that don't overly-humanize them. This is most of what I do in my own practice, at least, though I wager that doesn't work for everyone. Certainly from a narrative standpoint, making the gods into characters that appear at a single place at a time is easier for a reader to follow.
Second, there was an interesting thought that was seeded in my brain from a podcast I listened to recently. Sometimes various god-concepts, particularly those of Paganisms, get criticized for being anthropomorphic, or projecting human characteristics onto the gods. Perhaps what we need to do more of is flip that around - say that it is the gods that project their characteristics into us. And if the gods are the foundation of reality, would that perhaps be the more accurate way of looking at it, as a polytheist? Something worth mulling over, at any rate.
