Kiss Rhyming Goodbye: Non-Rhyming = Angry Rant?

Consider this poem that I'm going to make up off the top of my head.

I think rhyming can be cheesy.

-- If they're supposed to have the best pizza...
why do they keep changing their recipe?

like a pizza that's greasy
It comes from Domino's
Yellow like cheerios
Just under five bucks
but I think it kinda sucks.

Ok awful right?  Now consider this poem I'm going to make up with even less thought put into it.

Domino's pizza sucks
because it does
I hate it because its so greasy
and you never get enough cheese
it's just under five bucks
I hate it.

(Special thanks to Dominoes Pizza for being a good sport.  Seriously I love you... well maybe not "Love" but I don't hate you.)

Equally awful, I highly doubt either one of these guys would win an award in a poetry contest.  But hey the second one doesn't rhyme so the author must have taken more thought and have some profound deepness to his/her words right?

I've noticed in the world of poetry there seems to be this... higher esteem put on poetry that doesn't rhyme.  I've submitted my work to contest and I constantly see the disclaimer "NO RHYMING POETRY" my question is... why?  Can a writer be just as profound and skilled in rhyming as one who does not?

Months later I see the winning entry in this contest that I've been barred from and it's like some 500 line rant with an "F" bomb or two in it with no attention paid to structure and a meaning so abstract that it's impossible to grasp why the poet is so angry or what he/she is even angry about in the first place.

Don't misunderstand me.  I appreciate all poets and their unique writing styles.  I enjoy reading work that's vastly different from my own and have even written non-rhyming pieces myself.  But personally I enjoy bringing a sense of order or rhythm to my poetry and I blame the engineer in me for demanding this out of my work... but I don't see rhyming as the devil.

Sure rhyming can bring along some cheesy lines... (Who rhymes cheesy with greasy anyway?) but if the writer is crafty enough it can make for some pretty profound and clever works of art.

So here's the question:  When it comes to Non-Rhyming poetry what keeps it from being just an angry rant?  

Question 2:  Why do people seem to look down upon rhyming in poetry?  


Feel free to deviate from these questions.

Also feel free to share your Domino's horror stories... (Just kidding Domino's!  Seriously your pizza isn't half bad!)  = )
