Encounter in the Mall

I was walking in the mall one day when someone in a kiosk stopped me. They had a new product that they wanted to sell along the lines of "clean flix", it was a dvd player that filtered your movies according to violence, language, and sexuality.
argument: The salesman said that too many movies now a days have inappropriate content and many people would like an alternative: movie filters that cut out, skip over, mute parts of movies they do not want to watch.
audience: The audience he assumed he was talking to was probably a very conservative mormon. (I did not fall into this category. I thought his product was kind of silly; if you find a movie offsensive, don't watch it. He even said "why do I have to watch a movie just because the director says so?" A little ridiculous to me.)
ethos: To his assumed audience, he probably seemed credible, a mormon man who was knowledgable in his product, intelligent appearance.
pathos: He would probably appeal to the emotions of his desired audience because he made references to the mormon church and religion.
logos: This would go along with pathos. If you appeal to one's religion, it will seem very logical to them.
effectiveness: Again, for his assumed audience, he would have been successful. I did not agree with him, but I not as conservative as most and do not feel movies need to be changed. If you don't agree, don't watch it.
