That hatred of disco possibly contaminated any other form of media which makes any blatant reference to disco. The biggest culprit would have to be the 1977 film Saturday Night Fever. Anyone who hates disco will hate this motion picture. The lead character (John Travolta) goes with his pals to the disco club, and does a lot of dancing to the Bee Gees and other classics of the genre. The soundtrack, including the famous title sequence, is scored with disco music, and only disco music. And, everybody dresses like they live in the 1970's. Three strikes and you're out!
All this, of course, ignores the fact that Saturday Night Fever is a pretty good film, and is, at the very least, a reflection of its time and place in movie, and music, history.
Travolta plays a kid, Tony, who leads a very boring life. He is not in school, he works at a hardware store for about 2 bucks an hour, and his home life isn't the greatest -- it's not nasty, but it isn't warm and loving either. The only love in his life is the dance club, in which he can indulge in his fine skills on the dance floor. He is the god of the dance floor to some -- one woman is so excited she wants to wipe the sweat off his face, and another woman tries her damnedest to get into his pants throughout most of the picture.
The kid is seen as the least-compelling child in the family. His brother is a priest, so of course, that means he's the better pick of the litter. This family structure looks rather weak when the brother comes home one day and tells the family that he's given up the church.
Tony gets the idea of participating in a dance contest. The winner gets 5000 dollars. He is persuaded to pick Annette, the rather determinedly lusty woman I mentioned earlier, as his partner, telling her that this is purely professional. Soon, however, he becomes entranced by another woman in the dance club. The woman's name is Stephanie -- Tony is intrigued, and tries to get some sort of info.
