Modern Art...um, what?

Okay, I know I'm going to get yelled at for this, but I need to say it...
Modern art. I hate it.
Okay, before you start writing your hateful comments, Listen to my reasoning.
I love artwork. And I believe artwork should be a free medium for any type of style. But Art is not only a bunch of shapes and pictires that are simply nice to look at. Art is a form of expression, a way to display a mood, feeling, event, etc.
Take The Garden of Earthly Delights for exampe. It is a compositionally moving peice of art, expressing Man's Lust. and it is also incredibly detailed and well-painted, taking Bosch 30 years to paint. it is in 3 pieces, each setting a completley different mood, but still clearly in tune with each other.
Now, let us compare such a peice to something I saw as I visited the Walker Art center.
the peice is simply a Urinal, as found in any men's public restroom, the only difference is that it has been spray-painted gold.
that's it.
And I suppose if you think about it, there is a little symbolisim there. But compared to the Garden, it is obvious which is better.
Then take another piece at the Walker.I swear to god, I'm not making this up. it is a plastic school chair with a box of tissues on it.
Really. This is in a MUSEUM. A WORLD FAMOUS MUSEUM. It really makes you wonder if artists are even...trying anymore. Can a painter throw away all his skill to send a message? NO.
Can an artist give up all his symbolisim for good painting skills? NO. clearly, the former is what the abomination at the Walker is a prime example of. Sometimes Skill and Sybolisim are good to mix, and often, the weakness of one can be covered up by the strength of the other.
A Chair and a tissue box though...that's fucked up.
