The idea that someone is a snob because they dislike generic looking artworks is a hilarious indicator of how far aesthetic discussion and standards have fallen. The word used to mean someone that looks down upon the popular arts in favor of more traditional/expensive/sophisticated art.
Now apparently it means having any standards or metrics of evaluation, period. Either you think everything is equal aesthetically, or you’re a snob.
Thankfully this kind of empty opinion isn’t convincing many people these days.
You might not be a snob, but you sure as hell sound like one. It's okay when other people like simple things that you don't like.
