That's a lot of words that don't really mean anything. Art being subjective means that you absolutely can critique "bad" art, not that you never should. I mean your word salad about "the effect art has on people" is literally saying that, just instead of talking about the art itself you're now talking about it's 'effect' (as if you would ever be talking about something else?)

McMansions are bad art because they have bad effects on the people who live in them and view them. People divide the things that cause good effects into rules and guidelines. This post then talks about those rules and guidelines.
