Mother and son in New Mexico face jail time for incestuous relationship

I get that. But it is still just the "eww" argument, restated in dignified language.

I don't see how my argument only amounts to reactionary disgust.

I was talking about family values between parents and the people they gave birth to, disgust has nothing to do with it.

For all I know this woman could have been really good looking and the sex could have looked like something from a great porn film, not disgusting at all, but despite this I think that it's more than likely this kind of sexual relationship is a result of failed parenting somewhere along the line.

Why do you regard it as "immoral", if both parties are consenting adults?

The yuck-factor is enough for me to avoid incest, with no appeal to morality involved.
