Transgender man wins women's 100 yd and 400 yd freestyle races.

Why not?

Should we go back to race segregation of the leagues as well? For fairness?

Is this competition unfair to white skinned people? Why not?

You're advocating apartheid or claiming black supremacy?

Biologically the only difference between those people and the white skinned people are the colour of their skin.

I'm not aware of Melanin conferring specific advantages, are you?

No I'm cross examining your position, and not understand why your argument only applies to trans in gender divided sports and not the fairness of race divisions. For example, the 100m elite is dominated by black participants.

Folks in thread would with the thin logic they have presented here have us believing that this matter of fact should force us to conclude that blacks competition in mens racing is unfair to white men, because the top tier (shown in the above image, the 2012 100m Olympic final) was dominated by all black athletes, they 'robbed white men' of something something.

If you find this argument repugnant you should, it's the logic racists used to segregate the races and it's the same boilerplate logic trans-exclusionaries are pushing now to exclude trans athletes from being athletes. They used junk science to argue physical differentiation between the races, too. History seems like it's repeating itself.

Are you arguing for the elimination of the female/women category completely and have one open competition? (which is what is inevitably going to happen for the male category in non-contact sports) If you want to argue separate leagues and an ability to cross those leagues, you should also state what those leagues should be and the entry criteria.

Ultimately the whole area comes down to being inclusive or being fair, both are not possible at the same time. Sports, over time, will come down on the side of fairness, it always has. There will be lots of huffing and puffing till that point.

(I would also add that a denser skeleton is an advantage even with reduced muscle mass and that lower centre of gravity will depend on height of the individual and those with a female pelvis will always be at a disadvantage at the same height due to a less dense pelvis and putting more stresses on the pelvic and knee joints during movement, which also burns more energy, due to the legs being at a greater angle by default).

Really, that seems to be the best outlook.

While enough states eventually 'ratified' the Equal Rights Amendment, it was slow-walked so it would never actually happen .... but I digress, this isn't a lecture about the history of the ERA in Congress or whatever, or the reason it hasn't been constitutionally ratified... The fact is a plurality of American legislatures eventually agreed that this should be amended into the constitution:

Equality of rights under the law shall not be denied or abridged by the United States or by any State on account of sex.

On its face, I would argue this will ultimately steers the culture toward the elimination of the division between the genders and the sexes both and towards the right of everyone to be an equal competitor.

We could debate all the reasons why black African American and Caribbean men dominate sprints and Ethiopians and kenyans long distance running but never the other way around when they are all black but that's a different subject.

Explain why the science around transgender is junk. I'm open to changing my position if rationale science supports it.

Include the data to support your position please.

Because if anything, the last thing a woman would ever want to win is Equality, am I right?

Your conjecture is not won out by facts on the ground BTW

Perhaps we should address why you presume so little of elite female athletes?

Where do come up with that notion from? As though there are not currently as it stands now, sports in which the top echelon is comprised of women athletes! #fearmongering

I didn't say that.

Which Olympic sports have women athletes competing equally with men? The closest might be the mixed events, defined by there being a limit on the number of male competitors in a team.

I said that (as have sports ruling bodies).

You got it!

Men and Women both get to compete in War, so I think they can adapt to the big wide world of civil contact sports, too.
