demeaning

How is it "demeaning" to say you are a higher rank in a game?

"Whether you were intending to or not, you were being demeaning towards your team because you decided to smurf and they disliked it enough to decide to report you."

So smurfing is bannable? How does losing respect for someone against the rules in the first place? I lost respect for my teammate since he played poorly is that now banable too? I know you want to ban me super badly for whatever reason but atleast let me earn it. Butthurt kids who hardly play are mad im a higher rank than him so I shouldnt be allowed to play? Atleast let me start out at my main rank then or just outlaw smurfing. This is some in between stuff that isnt even logical.
