Because a scientific text is based on observable facts and repeatable experiments... things like that. God is based on myths and opinion... Nevermind that the main religions put women in 2nd place, so why any woman who support that is beyond me.
There ARE things we believe that have no scientific text, because, scientific text is not the only form of proof. In fact, unless you conduct the experiment yourself, the people doing it could be fabricating or lying about it, so, maybe we really do not know what is fact or real, ultimately.... I'm not saying think a certain way, I just thing we should be open minded to all possibilities, proven or not.
I'm not a fan of organized religion. That being said, I think there needs to be some sort of order in the world and in society for things to work well. I am married and have no problem deferring ultimate authority to my husband. That being said, we work as a team, but no team works with two leaders. Someone has to be the tie breaker.
