Definitely yes. However, I went to a couple of meetings a few years ago, and there was a regular attendee who had severe stuttering problem, and he looked like a typical dork. To my surprise, he didn’t hesitate to ask questions to the presenters. He asked more questions than the rest of us. It was painful hearing him talk, but that didn’t stop him. Later on, I found out he was married and having an absolutely normal life. I admired him so much, still do.
