I was a child when Danny La Rue was around, I suppose I was aware in my child like brain back then that he wasn't an actual woman, but a man dressed up as one, a sort of glamourous pantomime dame if you like. In retrospect my thoughts were Why does he do what he does, I don't know any women who looks and behaves like that and in dressing up in such an exaggerated way he came across in my mind as ridiculous and annoying.
Moving on. as an adult I discovered Paul O'Grady and did like his acid tongued "Lily Savage" persona and by then I think I even recognised the type.
I do think drag queens parody women in the their over the top exaggerated way, although I have to say that these days the look exemplified by Kardashians/Katie Price/Towie et al give drag queens a run for their money in how they present themselves in that absolutely nothing is natural.
Anyway one has to give it to drag artists some have the most sublime pseudonyms such as "Betty Swallocks" far more interesting than some bog standard moniker like Brenda or Maureen! and frankly yes that name is a piss take, but it's also very funny.
