Orwell was a Socialist, something they invariably leave out when they invoke his memory and steal his quotes.

"Eric Arthur Blair (25 June 1903 – 21 January 1950), known by his pen name George Orwell, was an English novelist, essayist, journalist and critic. His work is marked by lucid prose, awareness of social injustice, opposition to totalitarianism, and commitment to democratic socialism." (emphasis my own)

from the Wikipedia entry

"Animal Farm" was indeed a satire on Soviet-style "dictatorship of the proletariat", which Orwell loathed, and which he saw as a form of state capitalism and no different from the tyranny he examined in detail in "1984" as well.

"The Soviet Union was a mirror image of Capitalism out of control",

But the Right quotes him, presumably because they have no other comparably articulate thinkers of their own. But they never discuss any of Orwell's other political thought, because

1) it may not fit in too well with their own

2) it is important to their narrative that any leftist, socialist, social democrat or anyone else even remotely critical of the Right's program must be a member of a monolithic, single-minded, uncompromising Communist front.

3) They refuse to accept or even recognize the concept of "democratic socialism".

In other words, they see the political spectrum as totally binary: The good guys (US) vs Them, (anybody who doesn't agree with US 100%). They will accept no middle ground.

Funny, this is exactly how Lenin and Stalin worked, too. They were harsher on renegade lefties than they were on Czarists.
