In terms of a formal definition? Yeah, obviously. That's what stutter is. But in terms of keeping me from things? Not sure I'd agree with that universally. It's sometimes in the way, but I manage to do most of the things I mean to do. Might take a little longer to get there - speech-wise - but still, that's not reason not to try. And of course, the people around us are relevant to mention too. A disability doesn't need to be construed as a lonely struggle. We can talk, and we can get help and understanding, and we can enter into relations that make it easier for us to stutter. A disability is a social thing, really.
