Imagine if you had to be judged by someone and they picked your absolute worst weakness, the thing you hate most about yourself, something beyond your control, something you have be afflicted with your whole life...and the person judging you, knowing full well that this is the case decided to judge you on it. That would be pretty shitty. Most non-stutters don't get it, so I think you can be forgiven, and actually commended for being concerned enough to ask this here. Stuttering fucking sucks. And stutters are already well aware of what is going on. So the take home is there was no benefit and there could have been no benefit from your comment.
