I shit you not. They're upset that Kermit, a piece of cloth with a dude's hand up his upholstered ass (get a prostate exam!!!!) dumped his piece of cloth girlfriend for another piece of cloth girlfriend.
Leaving his long-term not-really-a-person love Miss Piggy for a younger, skinnier, hotter not-really-a-person pig. Granted, the new hottie IS a Ginger, and no man can resist a redhead. But c'mon, this isn't really something to get bent out of shape (see what I did there?) over. They are muppets. Muppets can't be misogynists because they are motherfucking muppets. They aren't real. Kermit isn't really a dude, Miss Piggy isn't really a dumped dame. Denise, while a smokin' hot redhead, isn't the femme fatale. There is no War Against Women in Muppetland.
