Here's a sympathetic perspective on some of these issues (note: I've known and worked with RMS since the late 1970s, e.g before he grew his hair long and decided to start the FSF).
From the article:
> ...crucial mistake: confounding individual virtue and purity with wider social liberation.
> ...the familiar liberal ideological mistake of lifestylism: the belief that changes in one's own personal preferences are the beginning and end of political action.
I hadn't really known anyone else like RMS, but in the mid 1980s I had a girlfriend from the Bronx. The first time she met her reaction was simply, "oh, one of those." She said she had grown up with a large number of guys just like him. And indeed, when I went back to the jewish neighborhood in the bronx where she had grown up there were in fact a ton of guys around his age, just like him.. Their causes seemed to be a mixture of judaism and socialism, but they expressed the same intensity and belief in the universality (within an interest group) of their cause.
This made him a much more sympathetic figure in my eyes. And once I could see this, I could see all sorts of people like him.
