To go to the nuclear option Stallman is pro voluntary pedophilia. This puts him so outside the mainstream of opinion that he might as well be shoving Jews into ovens himself.
The honesty is extremely refreshing for a small subset of people who will be fanatically loyal to him. These people will also be some of the most talented and difficult to work with, much like Stallman himself. In my circle of friends technical competency is directly proportional to your agreement with Stallman.
