The question is why do you find it amazing that there are so many tallented woman?
More than half the population are female.
If the same proportion of men and women are what we would describe as tallented,why are there so many men performing in relation to the number of women there are performing?
Also I think that women performers are often judged by other criterea than the tallent that they display for singing or playing.
As a bloke I am never made to feel that if I were slimmer,prettier or dressed more sexily i would recieve a better response to my performance.
Maybe I would but I dont feel pressured to change myself too achieve more acceptance.
But then I am a bloke so maybe a womans POV would be more valid?
