On point number two, I mean that’s probably because most industries, especially media, have been dominated by males for decades and are just now having more female presence in the last decade in greater, more pronounced roles and numbers.
Well I mostly meant the characters themselves are male projections as a result. So they are effectively dudes with curves a lot of the time. I'm having trouble thinking of exceptions who aren't caretaker types like Deanna Troi. I probably don't read enough contemporary fiction.
