Theres two ways of getting respect, commanding it, and demanding it. Commanding respect is garnering it through action, leaving it up to people to give it to you on their own terms. Demanding respect is literally forcing people to give to you, people who do this arent respected in the first place.
JC, Danny, JTN, etc command respect, and they can do this because people admire/are inspired by them in the first place. Without admiration its impossible to command respect.
Ave demands it, because he knows he has little to no status in BR. Notice he always has to point how much of a "man" he is? Hes "good" at what he does, but he isnt inspiring. People respect him as a man (which is good), but not his vocation.
