[The Might]

Very interesting posts, and also very interesting quotes

I liked the point made about the spiders being the perhaps only entirely matriarchal society, and I believe this is quite possible

As far as Easterling or Southron communities are concerned I am quite sure that they have a fully patriarchal society. Because of a less developed society I would expect that womed had less rights in the east and south then in the more advanced north-west part of Middle-earth.
The same would go in my opinion for others such as the Beornings, the Woodmen, the Woses or the Lossoth.

Varda however seems to be viewed as a type of matriarch by Elves and worshiped for kindling the stars in the sky.
