Old Europe and male-dominated IE?

Dear Indoeuropeans,
I'd like to know very much your opinion of Marija Gimbutas' work,
especially her book 'The Language of the Goddess'(In Germany: Die
Sprache der Göttin, bei 2001). Archaeologists seem to frown
continuously when they hear her name, but I admire her work very much,
especially her ability to see (and show her readers) similarities in
European Neolithic arts and their - non-language - meanings (she also
adds Lithuanian - and other - folklore in places where I can see the
similarity, very interesting). She opened my eyes to the fact that
before humans used writing to convey their languages - for what reason
ever - they had other, rather symbolic - means to express their
religious beliefs or their adoration of nature and life.
I find it especially important to note the fact that in the substratum
'Old European' regions men and women seem to have lived on in equal
status, a fact that may have been one of the reasons for its longevity.
But is it true that Indoeuropeans were male dominated as I have read
again and again? If yes (judging from archaeological finds - but they
are very much subject to modern interpretations): does this fact show
in PIE/early IE languages?
And I don't mean the fact that there was a male god 'ruling' the IE
pantheon (because that's probably interpretation again), I'd rather be
interested in more general proof (e.g.the use of a male pronoun if
speaking about a mixed group or other 'male' generalizations). Somehow
I'm not convinced of the 'male dominant' IE community yet.
Looking forward to your opinions
