(And seriously, if that was actually Gaiman's answer quoted in the screengrab, it just seems like a condescending British way of saying "You're interrogating the text from the wrong perspective." You can't write a book making every effort to be 'ambiguous' and then retroactively insists that the textually specified 'right' ethnicity is so important that anyone who disagrees read the book improperly.)
