When I studied computer science at university, one of the head lecturers had a stutter. It wasnt a blocking stutter, he just repeated the sounds a lot. I would like to get into teaching, but I can barely speak infront of groups at all. I think most intelligent people understand, it not our fault. But yeah there are some simpletons that think we're "retarded" or whatever, you just have to laugh in their face and continue with life.
