The long-lasting relationship between Eric Forman and Donna Pinciotti provided plenty of headdesk-worthy moments of misunderstanding between the two, but more often than not, their relationship was informed by mutual respect and humor… and, you know, their smoke circles.
But in the episode titled "Battle of the Sexists," everyone flipped out about Donna beating Eric at a game of basketball. At first, Eric is surprised by his friends' incredulity over the loss, but Hyde, Fez, and Kelso proceed to make fun of him and imply that he's been emasculated by his girlfriend's skills on the court. The ladies don't help matters much either, as Donna's friend Jackie says that Donna's athleticism is going to be a turn-off and harm their relationship, and her mother champions the idea that it's a woman's responsibility to make her man feel superior by pretending to be meek and in need of his strength. When Donna says that the equal rights movement is rapidly trying to undo those misconceptions, her mother shrugs off that forward thinking and basically calls her a crazy cat lady in the making.
Not only was this not the picture of modernity on anyone's part but Donna's, but it furthers the troubling societal notion that it is acceptable for men to be intimidated by strong women and that women should pretend to be less competent to stay in a relationship. Yuck.
