Duane D. Freese shows how far we've gotten from our basic principles by suggesting that cloning should be banned until the proponents prove it shouldn't. The basic rule of freedom is that you're presumed to be free to act unless and until you prove that you're not dangerous.

It's a very compelling argument. Why should any regulation or prohibition be allowed without a showing first that there is a real threat of harm, not just a science fiction scenario. Brave New World is, after all, still fiction.
