Still not sure why we're putting Daily Mail *and* journalist in the same sentence?
They protect power and wealth of their owner at all costs. That's all.
Media reform to stop a tiny amount of people owning the vast majority of our media urgently needed.

Israel is the problem. Jewish people are not the problem.

@yvalley @KirstiMiller30 Did you read the post at all, Amanda? SRY doesn't determine sex & so women who may not even know they have the SRY gene would be excluded simply for having the gene.

@KirstiMiller30 How is it misguided, it will keep the cheating men out of women's sport??

“Mandatory genetic test for women athletes is misguided. I should know – I discovered the relevant gene in 1990!!!”
Professor Andrew Sinclair is Deputy Director of the Murdoch Children’s Research Institute and the Department of Paediatrics at the University of Melbourne. He discovered the human SRY gene and has continued to research gonad development for over 30 years
"The IOC states that SRY gene is a reliable test for determining biological sex and therefore who can complete in women’s events.
However, this policy is based on the overly simplistic idea that the presence of the SRY gene alone is equivalent to being male.
Male sex is much more complex, involving multiple genes other than SRY in developmental pathways as well as hormones. The presence or absence of the SRY gene does not determine the range of human sex characteristics. Individuals with differences of sex development may carry the SRY gene but develop either complete or partial female bodies while others develop male bodies but lack SRY.
All the SRY test tells you is whether or not the gene is present. It does not tell you how SRY is functioning, whether a testis has formed, whether testosterone is produced and, if so, whether it can be used by the body.
The SRY gene alone should not determine who can compete in women’s sport."

Additionally, geneticist and anatomist Murray Barr, of the eponymous Barr body, requested sport officials stop using the technique. “Buccal smear testing in the area of athletics is totally inappropriate,” he wrote. “Its use in this way has been an embarrassment to me.”
The @ioc return to genetic testing revives one of sport’s most damaging regulations.
The SRY test erroneously assumes that a single gene can definitively identify sex. Yet, science has never supported that claim.
Women with DSDs may carry the gene but develop as females, just as some men may lack it but develop as males.
Coventry is wrong when he suggests that sex testing protects women’s sport. The reintroduction of these tests does not mark scientific progress, but institutional regression.
Sex testing has not, and will not, preserve fairness. Instead, it has caused and will cause irreparable harm to countless women.

EVERY single one of us has a body that is used to producing a given level of endogenous T (which fluctuates throughout the day, and day to day), but it's within a pretty tight range.
That's your body's 'set point' for T.
The reason EXOGENOUS T is banned (as doping) is that when you ADD testosterone ABOVE your set point, then you are able to get a likely performance benefit.
It's not because it's exogenous; it's not because you went from X to Y nmol/L. There's nothing special about Y nmol/L!
There's no effect for one person naturally having 5nmol/L and another person naturally having 30nmol/L.
The absolute values of an athlete's set point has NO RELATIONSHIP to performance.
But if you take someone with 5nmol/L and give them the equivalent circulating T of another 5nmol/L, then that athlete will very likely gain a performance advantage.
It's NOT that they got to 10nmol/L. It's that we've ADDED above their body's T set point.
The converse is also true: when you take an athlete with a given T set point and REDUCE the T (medications, surgery, cancer, accidents, etc), then that athlete will likely SUFFER a performance deficit…..this is what explains trans women on HRT getting slower.
It literally has NOTHING to do with dropping below 10nmol/L or even 5nmol/L or even 1.8nmol/L (the geometric avg for c1sfemales).
It's ENTIRELY that we reduced that athlete's T below their natural set point.
Also, EXOGENOUS T above an athlete's set point is dose-responsive: more T, more effect (not linear, though, and there are diminishing returns...and...like...poisoning).
Same with REDUCING an athlete's endogenous T from their set point.
So if an athlete, through cancer or an accident, say, loses half of their unaltered endogenous T production capacity...if we ADDED BACK what they lost via exogenous T, there would be NO NET change in their performance!!!
They literally studied this.
The FALLACY is when people wrongly extrapolate these facts about changing an athlete's T vs their set point, and thinking that athletes with more UNALTERED endogenous testosterone will have a performance advantage than other athletes with lower unaltered endogenous T.
NOPE!
So NO there's no difference to our cells with respect to endogenous vs exogenous T.
No relationship between unaltered endogenous testosterone and performance.
There IS a clear relationship between RAISING or LOWERING circulating T in an athlete from THAT athlete's set point.
Also, NO your body does not 'remember' testosterone from 10 days or 10 years ago.

Dear gender-critical campaigners,
When a girl is stopped and asked to justify her body to a stranger, pause for a second and trace how that moment became possible.
Policies were demanded. Lawsuits were funded. Endless suspicion was normalised. A culture formed where womanhood became something to interrogate rather than live inside.
So when scrutiny spills beyond its original target and lands on daughters, sisters, friends and strangers, the question is not who created it. The trail is visible.
Movements that frame identity as deception eventually train society to doubt everyone. The net widens. The gaze hardens. No one remains untouched.
If a young woman is made to feel unsafe, humiliated or exposed because she does not fit someone else’s checklist, that is not an accident. It is the foreseeable outcome of a system built on suspicion.
This is the reality of winning an argument at the expense of trust.
Congratulations on the victory.
Now look carefully at the cost. It is already happening.

Heidi Bachram has repeatedly gone after Jewish people who oppose Israel’s genocide.
Including this Holocaust survivor.
Beyond gross.

Pro-Pals grip the keffiyeh like it’s a religious object. This movement is a cult.

The fact that organisations that are funded by billionaires can just destroy any progress in society within a few years and there is nothing we can do about it, should be way more alarming to people..

Imane Khelif is not trans. Even if she were she wouldn't deserve the hate she gets, but Khelif is not trans. This has been definitively proven. These people do not care about women, they care about inciting hatred & profiting off of it.

I’m a feminist and this woman deserves an apology.
