Biblical

Most of you here have read the bible. I'm pretty sure of it. So have I. Cover-to-cover, several times. Highly engrossed each time. Learning, face scrunching, etc...
So...here is my question to YOU...
How do YOU, based on your faith and belief, choose what to take from it as God's law? Am I the only person who can't get down with a lot of the stuff the bible states? Take that part about being dirty during Midol Week or that part about a man being able to stone and return a woman in disgrace to her father if she's not a virgin on their wedding night...I mean...I know yall don't get down with that stuff either right? Even though it is in the bible right there for all the world to see.

I remember someone with short hair telling me once that I shouldn't cut my hair because it was a sin. The irony of that one STILL floors me. 
That whole "obey" the man thing? I've seen lots of bat shit crazy azz men try to make that one stick because it is supposedly in the bible. Hell...truth be told I remember my father beating the shit outta my mother quoting that one. 

So again...my question to you, as I know many of you are Christians...how do you pick and choose, from the bible, what to follow as God's law? How do you justify to God and to yourself what to allow to "evolve" and what to follow to the letter?
