Unintentionally Unsympathetic / The Big Bang Theory

• Leonard, Howard, Raj, Penny, Amy, and Bernadette are supposed to be sympathetic for having to put up with Sheldon. The thing is, they're no better than him and enjoy tormenting him, bullying him, and insulting him (and each other) to his face. This also makes the many, many episodes where they "stand up to Sheldon" unsatisfying, they rarely if ever take his Jerkass behavior lying down and they come across as massive Hypocrites who can dish it out but can't take it.
• "The Panty Pinata Polarization" has Sheldon and Penny getting into an Escalating War over the rules at Sheldon's apartment. We're supposed to side with Penny, but she's acting just as awful and petty as Sheldon, taking advantage of his many quirks to drive him insane.
• Another example of Penny being this comes in an episode where Leonard sneaks a look at and fixes her bad history paper. She gets angry at him because she wanted to do it herself... then proceeds to enlist the help of Amy and Bernadette to rewrite it just to stick it to him. Hypocrisy, thy name is Penny.
• Howard is this in "The Apology Insufficiency", where he gets ticked off at Sheldon because Sheldon accidentally told a government agent that Howard crashed the Mars Rover trying to impress a date, and as a result, Howard didn't get security clearance to work on a project. Howard was the idiot who crashed the Mars Rover trying to impress a girl in the first place, and he didn't even have clearance to enter the control room in the first place. Sheldon told the agent - by accident - something completely true about Howard that demonstrates that he is indeed an irresponsible person who really shouldn't have security clearance. And yet we're supposed to side with Howard.
• Amy in "The Habitation Configuration", where she acts like an enormous Jerkass towards Wil Wheaton, and yet when Sheldon is understandably annoyed he and Wil are treated as the ones in the wrong.
• Raj after breaking up with Emily. He spends the rest of the episode as a thoroughly depressed mess, but he only broke up with her after obsessing over another woman (who clearly told him she wasn’t interested) for days before breaking up with Emily right before Valentine’s Day. He then went crawling back to her when this stupid decision blew up in his face. All in all, he comes across looking more like a sleaze than someone you should feel sorry for.
