As you know, there are two kinds of people, those who divide people into two groups, and those who don't.
I'm the former.
And one of my favorite divisions is: those who want to control other's lives, and those who don't. I'm the latter.
A good example is the German cannibal
case. Some people see it as an obvious great immorality to eat a human, even if you have his consent, and think this should be stopped by law. I don't see why. People's lives are their own.
Of course it should be clear that subject must be in his right mind and consenting. I guess it's a sticky point because most people can't reconcile "right mind" with "consenting to be eaten". But we'd all do well to not equate "abnormal" with "sick" or "sinful", and particularly not with "must be illegal".
I can't imagine why anybody would want to be eaten or to eat somebody. But it's a great big world out there, and personal liberty is one of our holiest ideals, and should be defended even in the face of things we may consider repugnant.
