I think you're taking something personally that isn't at all intended that way, and I think that's making it difficult for you to appreciate the nuance in the statement to which you've responded. I understand why and I don't blame you for it, but I hope you're able to take a step back from the passion of the moment and reconsider; on the one hand, I think there's useful insight here, and on the other, I know it's not pleasant to feel yourself put so thoroughly on the defensive that you have to respond this aggressively, and I'm sorry to see anyone go through that, especially when it may not actually be necessary.
'jerf didn't say that academia is evil because Stalin, but rather that intellectualism which becomes too far divorced from reality can be an extremely dangerous force; he cited Soviet central economic planning as an extreme example of the sort of danger to which he refers.
I don't think it is controversial to say that Soviet economic policies were derived primarily from a political theory which was developed by people whom it's accurate to describe as "intellectuals", in the demonymic usage we seem to be taking as conventional in this thread. I also don't think it's controversial to say that these policies produced widespread, severe privation among the population on whom they were tried.
And I don't think it is accurate, or fair, to say that 'jerf meant this example as a general indictment of modern academia. Nothing in his comment seems to me to suggest anything of the sort. But I can see how, if I were myself an academic and an "intellectual", I might take some of what he did say as a very direct attack on my identity and sense of self-worth, and respond to that rather than to the arguments actually being made.
I hope I'm not coming across as patronizing here. I'm really not trying to be. It's just that, as a tradesman, I don't really have a dog in this fight, and as someone who's worked among academics in the past, I've had the opportunity to develop some insight into some patterns of thought which people who work in that paradigm might share. Among those, I think, is a general feeling of being constantly under attack by a populace which is both ignorant of what science and academia actually do, on the one hand, and on the other deliberately misinformed by a variety of demagogues for their own political benefit.
It wouldn't surprise me to see someone, who is accustomed to what I'd almost call this siege mentality, to react aggressively to anything which looked even a little like a critical analysis of the value of academia or intellectualism as a whole. It's very natural to respond in such fashion to an attack on one's livelihood. But I don't think what is going on here really is such an attack, and maybe the conversation we could all have about what 'jerf is saying would be more interesting and mutually satisfactory than the one we currently seem to be having.
Either that, or I'm completely wrong about what's going on and I've totally misread the entire situation. I don't think that's the case, but how can I be sure?
