The commentator mannykannot didn't really comment on the politics other than to agree that 1984 is a criticism of Stalism (which... I don't think anyone would argue with?).
Orwell also wrote "Animal Farm" which is a criticism of Fascism, and Asimov leads with this.
What nl is attempting to do above is the latest iteration of what Animal Farm and 1984 both received from those who could not stand the spotlight of their scrutiny: Claim that the target is something else, and/or that Orwell's attacks are so pedestrianly obvious (since "everyone knows" that Stalinism is bad) as to be pointless.
Um wow talk about bad faith!
Actually it's been about 35 years since I read Animal Farm, so I took what the review said as valid.
(Just pointing out the fact, not at all agreeing with the vile accusation against you.)
