Yes! even if its a boy or a girl, a father is as important as a mother.
lesbians, maybe, but the child would not have a father.
I'm 15 years old, and I would not have two mothers or two fathers, I (and every childs, teen...) should have the right equilibrium, a mother and a father, that whats I have also.
For me, having not the right equilibrium, I would call that, as in chemistry, an energetic material, unstable, as nitro or even more like nitrogen triiodide...
