That line is so strange. Like, Gene Roddenberry and the show writers very intentionally put a woman as 1st officer to make a point about humanity moving past gender divisions. So why undermine what they were doing with a line like that?
Did they feel like they had to call attention to it because audiences at the time wouldn't accept it?
Was it a character flaw they were trying to show in Pike to bridge the gap between the 1960s and future?
Or was it truly just casual sexism that slipped under their radar somehow, despite their intentions?
