Hilton is the perfect People/US/Parade celebrity - famous for being famous. She defies any sort of intelligent criticism since she doesn't do anything (as the author points out).
She is also the perfect mirror to hold up to society - people who take an interest in Hilton frighten and sadden me. I will refrain from stereotyping those who follow empty celeb gossip but I think we all know the sort. There are so many other things to learn and do in this world.
