Given the state of the world, it's irresponsible to not have kids -- if you're a maker, giver, and lover of the neighbors, lands and wildlife surrounding you.
If you're a doughy-handed politician or jr. totalitarian central planner, be my guest; don't have children.
Let the adults and our awesome kids take care of the planet. You've tried to ruin it; we'll fix it. Your time is done.
