Hi! I’m Doug. Vocal in this instance means Sean is passionately expressing his opinions about the subject.

Vocal means expressing his own arguments regarding with the matter. 😊

This is usually when someone expressing opinions and complaints in speech. Another one we use is "has a lot to say". For example "Shawn has a lot to say when someone disagrees with his opinions."

He argues with them. He expresses his feelings with his words to them.

expressing your opinions or views about something either defending yourself or letting the person you are talking to know how you feel about something.
