I am going to get philosophical on you today, so please bear with me.
One of the arguments against the childfree philosophy is this: "If everyone felt the way you do, the human race would die out."
True. And this is a bad thing, how?
Perhaps this makes me a nihilist, but unlike many people who operate on the assumption that it is of upmost importance that the human race continue in perpetuity, I do not share that assumption. Now, before anyone gets their knickers in a twist over this statement, let's take a rational look at what man has accomplished during his tenure on earth. Yes, he has made many advances and discoveries, but all of them have been in his own self-interest, not in the interest of the earth or its other inhabitants (unless you count advances he has made to undo his own damage). The planet and its inhabitants were just fine before man came along and didn't need any of his help. And to the larger universe, man is just a spect of dust, if that.
The problem with humankind is that our sense of self-importance is completely blown out of proportion. Just as we can bend over to look at an ant hill and marvel (and snicker) at the thousands of ants scurrying around with a great sense of purpose, so too are we just scurrying ants in the big picture. And like ants and all other living creatures, we eat, sleep and mindlessly breed, and then congratulate ourselves for doing so, as though it is some great, beneficial accomplishment.
The truth is that man is a scourge upon the earth. He has done more damage than good (again, unless you consider benefitting himself as a good, or undoing his own damage as a good). He has raped and polluted the earth, replicating himself and spreading like an agressive cancer. He abuses nature, animals, the environment and even others of his kind. Despite this, he is unwavering in his fundamental belief that replicating his kind is priority #1 and that people like me are deeply and fundamentally messed up.
Now, before anyone tosses the Bible at me and God's commandment to "be fruitful and multiply", you can spare yourself the effort. I believe in God, but not the manmade version most people believe in, and certainly not in the manmade writings that people pass off as the word of God.
The God I believe in would never order destructive beings like us to replicate uncontrollably, destroying all his other creations in the process.
