Ganesh, Is That the Name?

Thomas Aquinas says other gods are demons. We see these different images of the one true father, and I wonder if Christians don't take that seriously enough. For example, who's that multi-armed elephant Hindu thing? Ganesh. If I remember correctly, he's the god of good luck. So he is a demon or a mere illusion, but any sort of religious reverence we may give to an illusion in that sort of form isn't demonic.
