You think you have it bad? Don't worry! I have been getting grief about Muppets and how much I love them since the 70s, and my sister (to this DAY!) still complains to me that I MADE her watch "that stupid Sesame Street and those [deleted language here] Muppet Show [another deleted word]." Yeah, she cusses a lot for a woman of 28...
Have you ever considered asking any of those freshmen and sophomores if they watch other Henson shows, such as "Farscape?" Perhaps if they knew of other things that the Creature Workshop did besides Muppets and Sesame Street characters, for which they are famous of course, then they might be a little more understanding.
Of course, you are always going to have your horrid little creeps who will put you down no matter what, but that is because they think their friends are going to put them down if they admit they really watch those programs!
By the way...my son, who is a senior in high school, said "Good for her" when I told him that you chewed out those nasty kids on the bus who put down Muppets.
See, you have LOTS of people rooting for you, even those who AREN'T on the site!
