So many reasons. But primarily, superiority in the arts and sciences. The secular end is all that really matters in religion - once you realize this, questions about the disparity of the sexes in religion evaporate like dew. Of course it was very different once, women were generally held to be holy, sacrosanct and the spiritual sex, but to be honest they ****** that view up themselves with the help of men who stood to profit greatly from assuming their roles as spiritual guides and oracles of God.
It's a hopelessly complicated situation to judge unless you can tell the difference between religion and spirituality. The former is modelled on the latter, but the systemization of wisdom, philosophy and spiritual knowlege (or gnosis) and their transformation into dogma are always done to bury the real reasons that reveal why men are regarded as superior to women in these matters...
A nightmare question. Believe me, you probably don't want to know the answer. Don't go there, take my advice...
Under the present system of things, which began six odd thousand years ago, there is no chance of that changing. Matriarchy always ends up as fascism in a monied system, money corrupts everything but the egos of men. It's, as I say, so hopelessly complicated as to be not worth bothering about. Console yourself with the conceit that women like men being in charge, women want men to rule society and the family, women want men to be captain of the good ship Mankind...lie to yourself if need be.
Why don't you? The hard and irrefutable evidence of Men's superiority over females in this world is absolutely everywhere, just look around you! They succeeded in their diabolical, misbegotten quest for total control WITH THE HELP OF WOMEN! They won the Throne, and now they're never going to relinquish it, EVER. All men are kings and gods now, and women either livestock in the great Market of Life or at best just loyal First Mates on good ship Mankind. Don't you get that? What's so hard to understand? Let it go.
The truth is this - women had the chance to be what men are today, and they gave it up for love. For love of Man. It's sad, it's shocking, it's inconceivable to us now, but that's it. And that sacrifice, however abused or taken advantage of by man, cannot be undone and is irreversible.
