Try Googling "transwoman sets new record" for some examples.

That would give me examples of trans women setting records, not men.

Explain the difference to me.

(Spoiler: I never get a clear explanation. From anyone. Not even trans-identified people are able to explain it. Therefore, I don't actually expect one.)

Man refers to someone whose assigned gender at birth was male, who identifies with that gender, and has not undertaken any efforts to change their physiology. (Cis-man) Or one whose assigned gender at birth was female, who identifies as a male, and, by most definitions, has undertaken efforts to change their body to match what they consider typical for male.(Trans-man)

Trans woman refers to someone whose assigned gender at birth was male, but identifies as female, and by most definitions has undergone some effort to change their physiology to match what they consider typical for another gender.

In this particular case, the people setting these records have undergone therapy that would make their physiology far different from a man. Whether their physiology is close enough to cis-gendered females to fairly compete, is another issue, but to judge them by men's standards would be clearly inappropriate.

Suposedly theres minor skeletion differnces too, and muscle ones as well.
Plus things like hand and feet sizes. Testosteron is a big one too, makes it easiler to develope the body muscles.

If your born a man, build up muscles and transition to a trans-women, and compete you have a unfair advantage compaired to normal women.
Even if you use hormones to keep your levels around where a women does.

Joe Rogan said its like a woman growing up, and naturally haveing wide shoulders, and being on steoroids to build up muscles (her entire life).
Even after hormone levels are equalised, you still have all that progress you made pre that, ontop of theres still minor differnces between the two.

Basically you cant be a trans person and compete on a professional level (atleast not if you go male->female), it hardly seems fair to the women of the world, that do want to play sports. Otherwise if theres enough trans people, you would see womens sports dominated by trans-women.

Basically I dont think trans people ever truely become men or women.
They become as close as possible, and are then trans-man or trans-women, which theres nothing wrong with.
They just cant compete in professional sports, for the sake of women, who were born women.

Trans-men (women who go to men) have all the dis-advantages of being born a woman, trying to compete against men, who didnt have these, and thus the chances of ever being able to compete on a fair playing feild are tiny. Thus they basically arnt something you can find.

Thats why trans-women are the ones setting records (men who go women).
They were born with the inherant advantages of being a man (size/height/skeleton/muscle/hormone/hand+feetsize) and only had to have a sex change and lower their hormones to womens levels afterwards.  However the equaliseing of the hormones isnt the entire story, they still have plenty of other advantages, or had them growing up, so after transitioning their still at a better starting place than women.

Thats why trans-women are setting records in women sports, and not the otherway around.
Basically if there was enough men who were trans-women playing sports, there would be no space for women in sports (who were born women).

sports must be locked to birth gender, otherwise women sports will eventually become pointless

Well considering the revenue generated by women sports compared to men unfortunatelly the women are very badly regarded. Don't know if it is because women expend less money on sports though.
