if you've had dealings with RMS and not found him a really serious pain I'd like to know.
I've only very recently had direct dealings with him, and I entered into that with some trepidation because of the reputation I've heard from people such as yourself.
Thus far, my dealings with him have been unexpectedly pleasant. It's unlikely, but I hope to actually meet him in person some day. 6 months ago I'd have turned down any direct dealings with him and probably avoided pretty much anything with his name on it, but a situation arose where my opinion of him was changed a little and that resulted in direct contact, and my opinion of him has changed from a negative one based on other's words to a positive one based on his own words and my own direct experience.
Your dealings with him are different to mine, but that's life. Sometimes some of us really rub other people the wrong way.
