Cartoon description

I tried to describe a funny drawing; could you correct my text please.

-This cartoon represents a couple of middle-aged American people who have just finished writing the phrase: "  no ground zero mosque"  on a banner. On the left, the woman still have a hammer in her right hand and a couple of nails in her mouth. On the right , we can see a man holding a can of paint and a large brush ; He seems to be shouting his opinion which is written on the top right : " we can't have no freedom-hatin'muslims desercatin' things we hold sacred" . He wears a white tee-shirt displaying an American flag and a Palin's lapel pin. I think the cartoonist drew it to make fun of typical Americans people, because they have painted their slogan on the US constitution.

On the right , we can see a man holding a can of paint in his left hand and a large brush in his right. He seems to be shouting his opinion which is written on the top right hand side... " we can't have no freedom-hatin' muslims desercatin' things we hold sacred" . He is wearing a white T-shirt with  an American flag and a Palin's button (usa)/badge (Irish) on it. I think the cartoonist drew it to make fun of average American people, because they have stupidly painted their slogan on the US constitution!
