I'm assuming the guy who made the post linked below doesn't allow any media in the home that includes alcohol, tobacco, tea, or drug use of any kind. And, to be honest, would have to avoid the movie being discussed due to other content well beyond anyone kissing. I mean, there is violence, including killing people.
Those are also things for which the discussion would be about what is not OK versus the timing of the act.
