Libertarian Perspective

I just ran across this blog which is discussing an interesting topic, i.e. why should public sex be subject to governmental sanction--or societal, for that matter. You have to read the whole thing to get the full flavor of the argument, but I now find that I am intellectually a libertarian on the subject, but would just as soon not see people coupling like dogs on the park lawn. It is just hard to rationalize laws against it.
