Malicious Compliance

I'm trans and I actually agree with you. I don't know the solution to make things fair, but I wouldn't want to use a strong biological advantage over someone else.

I see it like if I'd been born with some identifiable and categorised physical advantage then I shouldn't be competing against people without that advantage.

It's debatable how big the difference is, however, and whether it's a gap easily closed or not. My thoughts are that there could be an open category where anyone could compete on the understanding that there may be severe biological differences. There's no easy solution :(

Edit: thinking about it, sporting competitions are more sex-catagorised than gender-categorised. I don't think someone identifying as female with no physical/medical alterations from a biological male form should compete with biological females and I don't think that should be controversial since the gender isn't what people care about there. It's the physical characteristics. In some sports that might provide an advantage, in some a disadvantage, but I do this it's important to discuss! At that point, however, you'd be better ignoring gender and sex entirely and only categorising sports like 'feather weight' or 'strong muscular development' or something
