I don't think I'd go as far as to say "any fight ever." A contest of brute strength, definitely not, but dirty fighting exists. A woman armed with a knife is not something I'd take lightly, and that's not getting into ambushes or creative use of the environment.

"5-foot-5 90-pound spy chick throws 250lb hired thug through a concrete wall" isn't going to happen. However, "5-foot-5 90-pound spy chick gets the drop on 250lb hired thug by hiding in a dumpster and jumping out to wrap razor garrote wire around his throat" is more believable as it allows small size to work as an advantage instead of a liability. Blades or other sharp objects get around the size/strength difference to a large degree, plus other weapons like guns exist (though I'm trying to avoid that since it's obvious and misses the upper-body-strength point).

Of course that's not what the narrative demands. Can't have anything suggesting men and women are built different, even if doing so would make for interesting, asymmetrical fight scenes. Have to have Joss Whedon-style "tuff gurlz" fights with a 90-pound waif punching grown men center-mass and sending them flying.

20-30 years ago the idea of a female protagonist was still relatively new and fresh. I rather enjoyed the different takes on how a woman could be the hero.

We had Charlie’s Angels, Wonder Woman, the million dollar woman in the 70’s. Spies. A super heroine amazon. And a bionic enhanced woman.

We had Ripley in Alien(s). Sarah Connor in Terminator. (Both examples of maternal instinct kicking in to kick ass)

This was all great and believable fantasy.

Today, however, it’s become a trope that’s boring and unbelievable. Mary Sue’s abound. One well trained woman could defeat an untrained thug, but I’ve seen so many shows where the woman beats up half a dozen professional goons.

It’s just not exciting. But it has to be maintained as a symbol of equality because the woke think women are just as strong as men and any word otherwise is blatant misogyny.
