If all dogs are mammals, then all mammals are dogs.
A few months ago I met someone with similar logic. They said:
Every boy who plays video games gets addicted to pornography.
Their Bishop told them that every video gamer who comes into his office to repent, comes in for a pornography addiction. Thus, all video gaming boys get addicted to pornography. Now tell me if I'm wrong, but aren't most boys who are working with their Bishops today, working on pornography problems? It is a serious problem, running rampant in the world today. It is everywhere you look. You used to have to go to a store to buy it, but now all you have to do is grab the nearest device with internet. What about all of the boys who are playing video games who are not going to their Bishops, because they don't have a problem? It is perfectly possible to play video games without getting addicted to pornography.
