In my universe, there shouldn’t be such a thing as “guilty pleasures,” which are “guilty” because the unspoken understanding is that you should be ashamed of enjoying them. Many are afraid to admit they enjoy reality TV because it’s supposedly complete and utter garbage, but it continues to climb in popularity, and new reality TV shows appear every day, each crazier than the last. Some people must like it, so many people must have the same guilty pleasure.
Perhaps we don’t admit our guilty pleasures because we might be afraid that others might think we’re stupid or wasting our time or money on what we enjoy. But I always say that it shouldn’t matter what you like and what other people think about what you like (unless it’s illegal or causes harm to animals or people).
The real waste of time is feeling guilty about your pleasures. The other waste of time is worrying about what others like and don’t like. Life is too short for that. So if someone likes reality TV and it doesn’t seem to be turning into an unhealthy obsession or causing them to act as crazy as the personalities on the show, that’s their business.
