If you're sufficiently in control of your actions to keep developing a major programming language, you're sufficiently in control of your actions to either not be rude while doing so or be aware that you're going to be rude and need to find a way of dealing with the situation (avoiding it, taking extra time before speaking, working with a therapist, whatever). Mental health issues don't excuse bad behavior. (Also, personally, if I were behaving poorly I would much prefer people to say "hm, 'geofft is being rude but I know he's a better person than that and can improve" and not "hm, 'geofft is being rude, that's just the way he is, I wonder if he's got mental health problems.")
