Trek does have a bit of a double-standard though. Compare the indignant disapproval of the women of Angel One to the tongue in cheek disapproval of the Ferengi's far worse treatment of their women. Bashir expresses surprise when faced with a matriarchal society.
Personally I think it's a numbers game. If they stuck to a stricter 50/50 casting policy we would see far greater diversity in the characters. Sadly, the default setting is male unless the character HAS to be female (wives, mothers, love interests) or unless somebody actively decides a character should be female. This is why the 2:1 (or worse) ratio has been consistent all through every version of the franchise.
