I believe the source of the “angry left” meme is projection. Their anger is matched only by their paranoia, and they convince themselves that it’s “the left” who hates them would just love to exterminate them all in Soviet-style camps. Given this alternate reality, they can express their anger without considering themselves “angry” because their anger is justified by the even greater anger of their “opponents”. At least, that is the impression I got towards the end of my “tenure” reading the “rightwing” sources (David Horowitz, LGF, Instapundit, Jeff Goldstein, etc…).

Do not go gentle into that good night,
Old age should burn and rave at close of day;
Rage, rage against the dying of the light.

Though wise men at their end know dark is right,
Because their words had forked no lightning they
Do not go gentle into that good night.

Good men, the last wave by, crying how bright
Their frail deeds might have danced in a green bay,
Rage, rage against the dying of the light.

Wild men who caught and sang the sun in flight,
And learn, too late, they grieved it on its way,
Do not go gentle into that good night.

Grave men, near death, who see with blinding sight
Blind eyes could blaze like meteors and be gay,
Rage, rage against the dying of the light.

And you, my father, there on the sad height,
Curse, bless me now with your fierce tears, I pray.
Do not go gentle into that good night.
Rage, rage against the dying of the light.

But there was nothing crazy about that anger, eh?
