Given how hung up you are with what other people enjoy (it's sooo gracious of you to not complain to them directly) and your judgement of the "quality" of that enjoyment, maybe you should try a little more of that introspection you seem to admire. As long as they're not hurting anyone else, their hobbies are theirs. Not everybody needs to be a philosopher for their hobbies to have meaning to them. This post isn't about YOU approving or accepting of other people's weird hobbies. It's about admiring people because of their enthusiasm, regardless of you or anyone else thinks. Focusing on your own judgmental attitudes about those hobbies totally and completely misses the point.
