They argue that the involvement of [trans women] in ladies' competitions is deeply unfair because they have a clear physical edge over [cis women] competitors.

Real practical pickle jar advice that always works: take a decent sized knife and tap the corners of the lid with the blunt end enough to dent it just a bit, one on each side of the circle or maybe 2 more should do it. It'll come right off after.
further additional advice: pretty sure 90% of opening a tough jar is persistence. if you're really crankin on that thang as hard as you can, there's a good chance you're making progress, even if it's not perceptible. at the very least you're stressing the metal or plastic and making it more malleable. there's a reason letting someone else have a go at it works so often and it's not just cuz they're stronger.
So...they wouldn't be able to go full falcon punch on a pool cue and knock a bunch of balls off the table, which I'm not that familiar with pool but I'm sure incures a penalty and would be super embarrassing at a professional level.
