You are of course absolutely correct the hardworking individuals in the adult entertainment industry do not deserve to be lumped in with deceitful scum such as the people at Ultimate Guitar . <| sep |> shoot them into spaceyou ' ve gone too far <| sep |> Poor things my left nut <| sep |> First off , to say that my argument is ' he doesn ' t have a qualification so can ' t argue on the subject ' is farcical because I would be talking about myself at the same time . I didn ' t say that . I ' m not sure where you got that from . I was referring to that fact that in this post , he criticised his critics for attacking him on the fact his doctorate is in physics , rather than criticising the content of report he produced . That is , trying to discredit him , not the work itself . You then proceeded to criticise his use of his title while writing in a separate field , and not the merits of the work which is pretty much the point he ' s making . It ' s perfectly normal and acceptable to use Dr as your title even when working in a different field . Not everybody chooses to do it , but it ' s incredibly common .
