This is an incredibly glib dismissal of an entire area of philosophy. It may seem intuitively obvious to you that there are not moral facts (it seemed intuitively obvious that the opposite was true to people even as recently as 150 years ago) but the debate is hardly settled by any intervening scientific or cultural or philosophical advancement. I guess read J.L. Mackie's "Ethics" for an introduction to the subject.
