Some selective parenting may not be a bad idea. Unfortunately, there exists people who contribute to the growing population by reproducing in order to either leave a mark on the world or because it is believed that the purpose of life is to reproduce.
So me, being a gay man, married to a gay man, with a dog, but no children - I am not really alive?
Not to mention, considering we have close (maybe more) to 7 billion on the planet, I think a little selective parenting is in order.
