The difference between all of the others–excepting religion–and hunting, is that the other statuses are ones that you have by virtue of being born, rather than through choices you make, or the way you’re raised. That is, you can’t choose the family that you’re born to, nor can you choose your sexual orientation. You choose to be a hunter though, and you can choose to not hunt. (Religion is much the same, but for some reason we’ve put religion on a different moral pedestal, even though it’s clearly a choice rather than inherent.)
