Not on this topic, but just a general idea of women dancers and such.
Does everything in life have to be intellectually stimulating? Not everyone likes going to university. They might find it extremely boring and want to do something else that stimulates another part of them . And it's not like they don't do anything. They go to the gyms and keep fit, making sure they stay in top shape. Some are even married and have kids. If they like doing that and it's not illegal, why stop them?
If forced into it, then yeah, I agree it is wrong, but if they want to do that because they enjoy doing it, I certainly don't have the right to stop them and I am happy that I don't, because that's just one step towards throwing your own vision of the world into someone's mind.
