I'm not implying anything about you. I'm just saying that it IS the typical response, and TYPICALLY it is said because the person doesn't understand art. I am surprised however that someone with an art education is of the opinion that art is either good, or bad based on nothing more than whether you like it or not. You like it or not based on whether you liek it or not, yeah

But that's not a measure of whether it's art. I like Top Gear, but it's not art. I like cheesy trance music, but that's not art either. It is a creative endeavour, and has it's own merits, but it' not art. I think you're right... the word "art" is not something you can just use in this context. It's too broad, and seems to segregate. However, it usually does distil down to this level when you have a wide range of experience and opinion in such a thread.
