I do believe the man should be "the man" (aka breadwinner, head of the household, etc.) and the woman should be his supporter, homemaker. Yes, it's based off my faith.
So, before I get flamed (I assume), I'm NOT saying women are inferior to men. I believe what I do because I believe it's what God intended. It's not an issue of physical proportions so much as it is knowing your role in this life as a man or woman. I know many won't agree with this, but I know a lot of Christians who do agree with this.
There are some Bible verses to back up some of what I am saying, and I want to reexamine them because it's been a while since I've looked at that part of Scripture.
