Why are some women such B1tches?

Why is it that when there is a child involved, women act like b1tches? What I mean by that is they use the child as a weapon, as leverage against the man. Just because the man and woman don't get along, the woman has to drag the child in and use it as a weapon. They refuse to let the father see the child. They run to the court house and get the max amount of money for child support instead of reaching an agreement with the father themselves. The father is forced to be a "weekend and paycheck" daddy. Women feel that it's the mans responsibility to provide all the financial support for the child. It's supposed to be 50/50 dammit! not 100/0. I hate women. I wish I was gay. Why is it so hard for men to get full custody? Women automatically get it but in order for the man to get it, they have to prove the mother to be unfit. Why doesnt the woman have to prove the man to be unfit in order for them to have full custody?Any thoughts?
