Can someone explain to me what thin privilege is??? That's a term I've just recently begun to hear and just exactly what privilege do we have?  Privilege is a "special" right given to a particular group. I have "abilities" obese people don't have but no special privileges.  I don't have to buy 2-3 seats on an airplane but that's not a privilege, I have the ability for my entire body to fit in one seat.  If there's a weight or size limit on something it's not a privilege for me to use it but an ability. They have the ability to join the "privileged" normal sized group - it's completely up to them.
