I'm not questioning your legitimacy as a person. I might question your empathy, or your understanding, or your logic, or your skill in some area, but not your legitimacy as a person.

I don't support the idea that people can be "not legitimate".

Everything you say in your response works equally well for abolishing any gender distinctions in sports whatsoever. Just do it by height and muscle mass, etc..

If that's your position, it is a radical change, but not obviously glaringly unfair. Just extremely different. Is that your position?
