I have one question that will put this matter to rest - regardless of which side of the fence you sit on.

Are there and equivalent videos of male piano players which focus heavily on the guy's shoes, arch on his back, and him rolling his hair here and there ... etc?

If the answer is 'yes', then it is fair (please post it too if you can find it). If the answer is 'no', well enough said.

PS: Before we go 'blaming' the artist, we may as well start off by 'blaming' the camera MAN (we know it was a man behind the camera, right) ... or wait a minute ... we are in 2019 and in these changing times, that could have been a woman too...
