But my point is, we’re smart enough as a species to not do that anymore.
Lol. Are we? Maybe it's just my small world but I don't see that at all. I encounter sexism CONSTANTLY. Hell, scroll down to the bottom of the comments on my main reply, it's right there for everyone to see.
The point I am making is that two bodies with similar bone density, muscle mass, testosterone, etc. are going to be physically capable of the same thing, regardless of their genders.
But gender does matter because one gender is predisposed to be bigger, stronger, have more testosterone, and has the ability to be stronger/build muscle more easily. I'd love to agree with you, that in a perfect world, gender didn't matter in brute strength, but it does. All things are not equal out of the box.
Now, as I have clearly proven, brute strength isn't everything, in fact most of the time it only means so much, but it's still there regardless. I think a more accurate statement would be something like "strength only gets you so far, capability is more important"
