My doctor charges for physicals, proof positive he is only in it for the money> and you work for free?
That is the worst analogy I've ever seen. If you had access to free medical care or paid medical care, you'd probably be an idiot for paying for it. If you can get Darwin's books for free, why pay for them? I mean, unless you're a creationist who has never actually Googled the web for information, but rather has relied on someone else to get it for him.
