I've written about this before on here. I used to be a middling badminton player back in the early naughties. Think, top men's singles player in Hampshire, that type of level. Solid, competent club player. The female world number 2 came to our club for an exhibition thing and I got to play a set against her.
Now, I'm not saying she tried her very hardest, but what I'm saying is that it would've made zero difference. I destroyed her. Technically she was a much better player than I was or ever could be, but she was so weak and slow. It was so weird to observe against in real time. To your average person the styles and speed and shots look exactly the same, but there's a galaxy between the males and females, in badminton anyway. Can't speak for tennis as I don't know the realities of the game, on court, in real time. Maybe it's broadly applicable, maybe it's not, but for badminton anyway, your competent male club player of any nation will destroy the top 5 world female players. And they won't even try hard.
A few years ago I watched the world number 1 female player from behind the court she was playing on. It was interesting tracking her speed and movements in real time. I was late 30s at the time and not picked up a racket in 15 years. But what I saw there, knowing what I know, I was still wondering what would've happened if we played a set. Realistically she would've smashed me, but by how much, I don't know.
Anyway, it's is, and always been a dumb debate. Anyone that argues otherwise invariably do so out of emotion instead of lived experience. And certainly never on a badminton court (or tennis court).
