Oh, don't get me started on feminist paganism and the whole "once everyone worshipped a mother-goddess and women were revered and everything was cool" thing.

Even in those societies where goddesses were worshipped on an equal level with gods (in most places where there is a mother/earth goddess to worship, there is also either a sky-father or a hunter/horned god who is just as powerful), there's no evidence for full matriarchy. Some places women had a significant role in leadership (a number of First Nations, for example), but there weren't all that many of them, and while a good many societies were matrilineal or matrilocal at some point, in almost all, power and property were held and exercised by men, and simply passed through the female line.

There are hundreds of great goddesses to worship, but please, let's be realistic about the cultures in which they were worshipped in the past.
