There are definitely some homosexuals that do seek to recruit teenaged boys. And that’s what the film gives a warning about.
It probably wouldn’t be an appropriate film to show today to kids, because there are all sorts of men practicing homosexuality openly. But when it was being shown, these are the kinds of gay men that we teenagers had to be aware existed when we were hitchhiking a ride or whatever. That’s of course another thing about the film, we kids used to hitchhike all the time back in the day. Teens today don’t do that.
