I believe the theory of this thread
Is make it rhyme, and keep your head.
So here is my response in verse -
when sung it might be even worse:

My country is perfect, in all of its acts,
like no other place on the Earth.
Don't say we're just human, you don't know the facts
on account of the place of your birth
you have nothing to say that's of worth.

My country is perfect for all of its faults,
that noone can mention but me
when they shoot up a school with a couple of Colts,
it's the price that we pay to be free
unlike pansies from over the sea.

My country is perfect, and you make me sick
when you say that at times we are wrong;
you say you're as bad, but that's just some kind of trick
like it's all been a trick all along -
No, I don't like your foreigner's song.

("The Route of the Blues" is the tune I have in mind.
If you don't know, some other you can find.)
