Nobody is doing that. I, for example, like plenty of things that I recognize as low quality.

I'm not entirely sure that aesthetic realism isn't true.

Which, that's not to say that if someone were to have a different taste than the "objectively correct one" (assuming that one did exist) that they would be wrong to have it, but I consider it to plausible that someone's tastes (e.g. mine) could be in some proper sense, "incorrect".

There are a number of topics where I feel like, if aesthetic realism is true, my personal tastes probably do not really match up with the true taste.
