I'll remove the whole sentence. Give me a day or two to source something which can be referenced and I'll do a swap. I'm actually not interested in arguing about peacock terms (quite ironic since all male editors here are peacocks by default and all the male musicians that have a biographical entry are also peacocks - I think you will find in nature that it is mostly the male of the species that does the big noisy or colorful display) or original research (quite ironic since no author of any work in existence has ever written a book that didn't contain original research). I challenge anyone to find a book (with references) of any kind  that doesn't contain one or two sentences expressing a personal view which therefore constitutes original research. We are in essence using references from peacocks who themselves have used unreferenced sentences to display loudly to other males their intellectual prowess.

Which seems to be what we male editors spend a lot of time arguing about on Talk Pages under the guise of rules and guidelines. lol
