His views may be extreme, but they are extremely well thought out, well justified, and well argued (as long as you don't count user-friendly presentation and being nice to people as necessary requirements for arguing well). He's not wrong about what he says and believes, and he's extremely consistent about that, but his priorities are a lot different than most people's. And the world's a better place because of his influence on many less extreme people with different priorities. Plus he has a great sense of humor, if you don't let him get under your skin: http://www.art.net/~hopkins/Don/text/rms-vs-doctor.html
