If people stopped having kids that would be fine with me, or they can keep having them I dont care.
When I was born, my mother took a couple years off work to stay home with me. Perhaps others should do that.
But if no one ever had kids again, then the human race will eventually die out. This does not seem like a realistic solution to the problem.
Do you really think the human race is going to stop having kids?

Of course not. With that said, its the way it is. Gay couple cant have kids or someone is medically incapable of having kids. Okay, that stinks for them, but it still doesn't take away from the rights of parents to be there for their child when they need to. Is this fair to the gay couple or to the couple who can't have kids? Nope, its not. But as you always say, "Life's not fair." (in some fashion). Society has determined that some privileges may be granted to certain people in certain situations. You don't like it, tough (just like you often imply). It's what keeps society running effectively, and that is more important than your individual right.
Just like new parents are granted maternity and paternity leave because we have determined that initially bonding with the child produces the best outcomes for the child and for society as a whole. As such, this trumps your individual right.
