It's more that I see the ultra-feminine, over-sexualised, glamorous stereotype of a woman as an imposition onto women's lives
yes, I agree with this
It's a bit like asking why Caroline Aherne couldn't have cast a real older woman to play Mrs Merton
I'm trying to figure out why I didn't enjoy Mrs Merton, but didn't find her offensive, but don't enjoy Mrs Brown, and do find it offensive...
Ditto Pantomime dame and drag
Even when they are not I don't get why it's funny.
I don't find drag in and of itself funny - I can find the acts funny, but the fantastical dress doesn't actually amuse me - it's more like a beautiful costume on an acrobat - the acrobatics are the exciting bit, the costume is just something beautiful to look at while they're doing it.
But the joke is that they're women with (usually) sexually suggestive, female names.
I've pondered this a bit - I think the difference is that the sexually suggestive names are sexual suggestions where they are the object - I think this is a place where their being gay is different to if a straight man did it - if they're making a joke about swallowing, it's because it's aimed at themselves, not at them doing it to someone else.
