When I was a liberal, I used to complain about children. How loud they were, how annoying, how they destroy the planet. There is, of course, some truth to this. But at its root, it is cynicism in the extreme.
Then I became a father and grew to reject these narrow, short-sighted, misanthropic views. Becoming a parent is part of the natural process of renewal that all humans need to witness and share. Seeing the world through the eyes of your own child erodes some of that cynicism and replaces it with joy. Parenthood is such an amazing experience. Almost everyone should do it.
