Cult of hate?-You cannot be serious.?I don't see any need to distinguish between pastiche that is specific or general. There's nothing wrong with pastiche, and there are a few fine works which have been labelled as such. Rodrigo's Fantasía para un gentilhombre is considered by some to be his best piece, and it's an arrangement of tunes by an obscure Baroque composer. Respighi composed quite a few of these sorts of pieces. There's also Warlock's Capriol Suite, and even before the 20th century you get composers labelling pieces as pastiche (such as Schubert's Overture in the Italian Style).
There's nothing wrong with composing in a derivative style. I think what grates quite a few people is Deutscher's divisive and honestly, very simplistic, approach to matters of artistic expression. I'm avoiding making further comments on her ideology or her music because, as I said, I'm not here to rain on people's parades.
There's been enough division around her on this forum, even a cult of hate. In any case, when I did put forth my opinions on her in a balanced way, there where attempts to draw me in to this ongoing war around her with the usual internet tactics (fallacies galore). I have no intention to do that again, also I'd rather discuss music that I like or at least appreciate in some way.
