Men will still be stronger at equal weight than women though the difference isn’t as drastic any more.

About martial arts in particular though women have an advantage when it comes to actually being mentally capable of learning proper technique early on. You can tell your ordinary 16yold guy as often as you want that they should trust technique, punch with their legs, etc. it won’t get through their skull and they’ll over-tense to “feel the strain” the moment you turn your back on them. They just love their 3rd class levers. Probably even makes sense from an evolutionary POV as doing things inefficiently is strength training.

It’s definitely possible for a woman to get better than a random street punk (though not with “feminist self defence” type of classes, those are generally bullshido). Against a properly trained man, though? Let’s say that the only thing my SO manages to be is a handful when I try to tickle her and it’s kinda hard to tickle when you don’t have a free hand.
