I'm merely starting from the observation that the best composers are indeed men.
It's clearly a complicated and open question that is likely the combination of many different factors. It's clear that - without attaching any value judgements - there are neurological differences between women and men (see https://en.wikipedia.org/wiki/Neuroscience_of_gender_differences).
Or maybe not, since they would have to study and compose romantic era music the way it was done 150 years ago to please Thal
There is no denying this, but the feminists will be searching for reasons until the end of time as opposed to just accepting the fact that compared to men, women are crap composers.
Women display superiority in many other disciplines including cleaning bogs, defrosting freezers and doing the dishes.
They can't be good at everything.
