Your response of "I'm always confused when people apply to MFA programs..." implied you're being dismissive about other people's genuine inquiries. Furthermore, your "Lord, please don't go by the ranking list, just make your own list and go by that!" response implied you're discounting the fact that (whether you agreed or disagreed with the list/methodologies) how ranking actually somewhat (emphasize the 'somewhat') determines the school's credibility of producing artists/designers. It's completely fine if people are questioning about the programs they're going to attend.
