Thats it? That response is a bit of a letdown (but in a way exactly what I'd expect from rms). It kind of goes without saying that you're going to be skeptical of things said by someone who disagrees with your philosophy, but I wouldn't fault him for using that as a preface to a discussion, except that's all he says. It make it seem like he just dismissed your message without giving it any thought. Maybe that kind of hypocrisy is needed in a advocate like himself, implore people to heed your message, ignore listening to anything that might change your attitudes.
