You did great. Don’t report him and do stick with the class. Rise above and don’t let this be a defining event. You’re bigger and badder. These misunderstandings do happen. I always stutter on my wife’s name when introducing her at fancy work events. People think I’m joking and laugh—even good friends from work. They just don’t know. It still stings but I see it this way: stuttering should be no big deal. So I’ll treat it that way, be patient with people who don’t know what’s up, and keep on stuttering.
