is gender inherent? or can it be manufactured?

Some people believe that you can parent children a certain way and they will turn out differently than they would naturally.  Like, if you raise your son more like your daughters then he will be less aggressive and more mild mannered.  I however, do not believe this is valid. I think that little boys were built to be little rascals and there's nothing wrong with that!  They have almost instinctive ways about them that make them the way that they are.  Sure some boys are more timid than others, but that's ok too!  Likewise, little girls are naturally going to be more nurturing and caring because that's how God created them to be!  I think it's silly that some people or rather parents think that they should try to change God's perfect mold for his children.  Each of us have our own personalities, and different quirks about us, but we are all children of our Heavenly Father.  We were created the way we were for a reason.  We all have a divine purpose!  Let's rise to it and make every day count!
