I'm putting in here what I wrote in my assignment ...
Ballet was deemed as a feminine art because ... that goes back a lot to when 'dancers' were deemed to be little more than demi-monde. (I am mostly writing of Europe/England here, I don't know so much about other areas of the world) Women who were the mistresses of wealthy and/or influential men.
I got this by googling "demimonde victorian times"
Demi-monde refers to a group of people who live hedonistic lifestyles, usually in a flagrant and conspicuous manner. The term was commonly used in Europe from the late nineteenth to the early twentieth century, and contemporary use has an anachronistic character. Its connotations of pleasure-seeking often contrasted with wealth and ruling class behavior.
The term 'demi-monde' is French for "half-world". It derives from a comedy called Le Demi-Monde, by Alexandre Dumas, fils, published in 1855.
The term was often used as one of disapprobation, the behavior of a person in the demimonde being contrary to more traditional or bourgeois values. Such behaviors often included drinking or drug use, gambling, high spending (particularly in pursuit of fashion, as through clothing as well as servants and houses), and sexual promiscuity. The term demimondaine referred to a woman who embodied these qualities; later it became a euphemism for a courtesan or prostitute.
Then, when ballet was 'invented' as a particular form of dance, the tendency was to continue that 'definition'. Dancers weren't 'respectable' (neither were actors for that matter). So of course those 'men' of society wouldn't appreciate men dancing ballet. That would appear to perhaps put a whole different slant on their own sexual preferences, and thus was unacceptable. So, also, any male persons who wanted to do things which were not deemed manly -- like designing clothing? *le gasp* *quelle horreur* instead of going out and blowing each other's brains out and doing things like that and pugilistic activities such as boxing (or wrestling which I don't QUITE understand but evidently that is a manly sort of thing) ... got off track there ... but LOOK at the game Creaothceann, where rocks fall out of the sky and 'men' have to wear cauldrons on their head and even then folks DIE in the game -- and IT is deemed a test of manliness and courage! HA.
Oh well, forget it. That was then, this is now. I think a fair test would be to challenge any 'male' person who denigrates any dancer who happens to be male (or female for that matter) to ... having a lesson with them. Plus perform a dance routine. Plus participate in a rehearsal. See who is left standing.
Of course, that won't prove anything. Just piss them off, I think. However, I *do* think that nature will take care of it, because stupidity doesn't last.
