My Favourite Show! [one of them]

A week or two ago, I saw a "Simpsons" episode from 1997. Homer met and became friends with a gay man for the first time--without realizing it right away. When he understood the truth, of course various antics followed! At the end of the show, some large credits acknowledged steelworkers of America; and there was encouragement to the effect of following their rainbow!? *** Have been aware that a steel mill town in the province of Ontario was involved in the gay rights project. And it's possible and likely steel mill towns elsewhere are involved, also!? [Did I hear Michael Jackson's father used to be a steelworker in a factory? Someone can correct me if I'm mistaken.]
