Regular worshippers at church are there because because they believe it is right. Not because they lack courage to go it alone.
Whilst it is true that there is still not gender equality in many churches, they, like many other institutions have some way to go. Look, for example, at the number of women MPs or women in boardrooms. One could throw one's toys out of the pram and announce that it isn't fair, or one can stay within an institution, organisation, church or political party and work for change from within.
