Thing is a strong female lead back in the day was.... still for all intents and purposes a female and it made sense. Doesn't mean they were not sometimes doing some rough and tough stuff, but they still seemed like women doing those roles.

Now adays in most cases a "strong female lead" just means a woman pretending to be a dude and they are basically interchangable.

That is what always got me about feminism.... if you really break it down most feminism is actually a celebration of manlyness weirdly and just forcing women to adopt male traits.
