John,
I can completely understand your viewpoint, and considering the mans POV, I myself can agree with you disheartment. Although I don't believe it's the most ethical of MJ to put his name on the blood, sweat and tears of the assistant designers, he admited to the in the "Butt Magazine" article below. However, from a Lady's perspective, Marc Jacobs is relevant, fresh (in American Design). His signature style proves his savvy in both Art and Fashion history, concurrently his referencing of several iconic (style and political) movements in Fashion prove his dedication to the art of fashion. So, no I do not believe that MJ is being Noble by vehemently agreeing to the notion that he abhors menswear (and fashionable men), but his design eye keeps both lines consistent with one another.
