I don't think I disagree with much of what Asimov is saying here! Aside from the silly bits about left infighting and scifi as forecasting (yawn), and the horrible recount of the Spanish civil war, I've made pretty much the same observations about 1984. It's nihilistic and reactionary, it's profoundly misogynistic and it reeks of contempt for the working class. It's also shockingly naive and paradoxically enthusiastic about the workings and effectiveness of propaganda and censorship. There's certainly nothing prescient about it. It's baffling to me that it's still popular with leftleaning people to this day.
The most generous thing I can say is that the book might have been intended purely as satire, and as such it would at least be coherent. But sadly I don't think this is how people tend to read it.
The thing is, the world in 1984 is feminist! as imagined by a bloke who hates feminism. Sex for pleasure is outlawed, makeup and dresses are banned, women look and act like men (and indeed are worse than men) instead of following their womanly nature. It's a feminist dystopia!
I mean, if god damned Asimov thinks your book is misogynistic, you know you've fucked up!
