I don't think the new fellow at McQueen is getting much love compared to Sarah Burton and it's not like Raf was immune to intense criticism either at Dior prior to MGC.
I don't think gay men expect women to come out looking like a Galliano couture show. Come on. I think it probably comes from their lack of understanding of how the fashion business works and is turning / how the dominant markets dictate what these fashion businesses cater to (i.e. logo merch pieces sell well in Asia and metropolitan cities and certain fits/lengths that do not complement the women body as well sell better in the Middle East). As I stated, the hate could be shifted more towards executives who are turning previously creative fashion houses into merch factories; do not let the clever marketing of "clothes for real women" fool you. I'm sure if the next creative director at Chanel or Dior churns out uninspired collections, they will get just as much criticism as VV and MGC (or in turn VV and MGC will get some post-tenure praise among the gays such as what has occurred for Sarah Burton).
Of course, there is the issue of sexism among gay men but...I think most gay men adore women because they adore beauty and value the power of femininity of women. You can't say men like Ghesquiere, Alaia, Elbaz, Karl, YSL, TF, Anthony V. do not adore women. And obviously their "gay vision" hit some cord because many "real" women did/do still love their creations (in both accesories and clothing propositions).
After my long winded responses on this thread, I still ask myself why exactly are we so concerned about protecting people, who make six to seven figures in their salaries, from criticism?
