I agree on that one. But on all the other stuff, I believe that both were inspired by The Craft, weren't they? I think I read that somewhere. Maybe in this post, I'm a little off. But the point is that both were inspired by the same basic thing and there are probably just coincidences.
In ancient pagan religions, which Wicca is based on, love is the great power that can overcome anything, including evil. Three was the perfect number and that's been brought even into the present by Christianity which melded with paganism in Rome when it was made the official religion. The Trinity was inspired by that number because there's no mention of it until after Rome had declared it that way and the following texts then mentioned the Trinity. ANyway, way off track. It all has its roots in the same place, so the main themes of 3, love and good vs evil are going to be the same. THe initials thing is cool though.
