I think everyone is able to judge what is and isn't art even if they don't have the "learning" backing them up. Because, like I said in my original post, what is and isn't art is different for everyone else. I don't like "modern" art (and I've learned something new from this thread about the term!), but I'm willing to accept that there was probably a lot of thought or emotion that went into creating it, and it's just not something I personally connect with.
