My hamster (human instinct) very definitely is. The rational me shouldn't be: I know I'm more than my reproductive organs! The problem is, on issues like this hamster is pretty loud, and it's not obvious on an intuitive level that "hamster terminal values" are actually "me-instrumental values" (since my life is not about placating hamster, but placating hamster helps me be happy and productive)!

I'm suspecting that most people don't have this kind of grasp on their hamster-minds though, and female hamsters are pretty destructive on these issues.
