It was, and from what I recall, it was the first TV show to have a major character being openly gay, causing quite a stir. We're talking about the seventies here, so that was something really big. And Soap also had a DS connection - it had an entire storyline wherein Billy Chrystal's gay character manages to have a child with a female character, and the baby eventually ends up being possessed. (Not because his father was gay, by the way.) I remember the "cliff-hanger" conclusion to one episode, where the baby's parents bid the child goodnight and leave the nursery, and suddenly things start levitating, windows blow open, and an evil, gutteral laugh echoes. It was really creepy and the audience reacted with a shriek of fear.
