See his "Man in Black" lyrics, in pertinent part:
...I wear the black for the poor and the beaten down,
Livin' in the hopeless, hungry side of town, ...
I wear it for the sick and lonely old,
For the reckless ones whose bad trip left them cold, ...
Ah, I'd love to wear a rainbow every day,
And tell the world that everything's OK,
But I'll try to carry off a little darkness on my back,
'Till things are brighter, I'm the Man In Black.
This Cash is clearly an un-American elitist: claiming that people are "beaten down", "hopeless", and "lonely". This is America! No one would be so cowardly as to be "bitter" or "unhappy"!
Barack Obama, take note. Unless you wear the Smily Face all the time, you'll just be some unsuccessful commie like Johnny.
