Modern art (poetry)

I don’t understand modern art.

A performance artist       printed on a Picasso
Wrote in the white       of a wrap’round face
His name.

Telling us       his amazed audience
That this is a message       to the poor miserable masses
About consuming       consumable colors
And pretty pigment       on parchment
How art is       an awful illusion
Admitting to us all       as if
Texting in a theater
Screaming in the cathedral
Urinating on puppies       (and perhaps)
Shitting on kittens.

And I do not understand modern art.
