I think so too, and dangerous at that. Of course there are extremes, and of course there are exceptions. But the moment you consider them not just worth mentioning but expedient to mention in this debate, you give them a disproportionate weight that simply doesn't reflect reality.
I've been rereading Discworld, and last night came across that lovely scene when Errol the swamp dragon fights with (OK, it actually emerges that he's flirting with, but ignore that for the moment, everyone thinks he's fighting) the dragon-dragon that's taken over the city. Errol's much smaller and weaker than "the king", but has supercharged his little dragon body to be able to dodge and weave and misdirect (AKA: it's skill against strength). As Errol appears to gain the upper hand by outmanoeuvring an enormous wing and the crowd below cheers, Vimes (captain of the city guard and sager than most) groans.
"Why?", ask his men, "He's winning!"
"Yes," says Vimes. "But the thing is, he needs to 'win' every single time. The King only needs to win once."
The same point's made in an Angelika Jolie movie I saw (forgotten the name). An abused woman trains for years to be able to fight her stalker and kill him in a fair fight to be free of him. And she does it - but only just. As he says, at the start, laughing at her professional fighting stance: "All I need is one punch".
However good she gets at martial arts, almost all women will be in the position of Errol the dragon, or Angelika Jolie's character. Those for whom strength would level the playing-field are truly, vanishingly rare, whatever their proportionate weight or achievements in the gym. And skill doesn't level it, it just gives you a better chance.
Sad, but, I really do think, true. It's a very hard truth to accept though, and also a hard one to really, truly, meaningfully test, even in the dojo. So a happier Hollywood fiction becomes confused with reality.
