I don’t care about his views on those kind of politics at all. But when it comes to free software he is an ideological maximalist. Take a look at how he uses computers personally, his values (at least currently) don’t fit in with most users expectations of what personal computing should be. His contributions aren’t in question, and his voice is a valuable one to have in the choir, but he’s not a person willing to accept a middle ground, and as such the RMS way of doing things is never going to be widely accepted.
