The sperm donors always tell children that it's all their mothers' fault, that the women are crazy and whatnot. If you're male-centered or a male in itself, you will want to believe him. As little girls, we are made to believe that a man's word weighs more than a thousand women's actions. You grow up seeing your mother sacrificing everything for you, taking care of you, but since we are not allowed to acknowledge reality, you will most likely hate her for what some testerical man says. I've had this experience, though the male's words had no value to me at all because I always despised him anyway, way before the divorce. Holding grudges saves you quite often.

A little note: I call 'fathers' sperm donors because men are not at the same level as women in reproduction. The male body doesn't know when a child shares his genes, or even IF. It is the woman who creates the life. So I take matters into my own hands and not call them that.
