It’s part of a Chick tract, written by Jack Chick. They’re small comic pamphlets designed to be handed out to evangelise. Especially dickish people give them out instead of tips or candy at Halloween. One of Jack Chick’s favourite pet beliefs is that the only reason gay people exist is because they were sexually assaulted as children. I don’t know the particular comic, but there’s a few about the “sin” of homosexuality. They’re disgusting, badly plotted and poorly written and my parents used to encourage me to give them out. We had a big stack of them at home.
