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

The irony is that this is the same person who coined the term “pundits fallacy”, is falling foul of it themselves…

Assuming that one's favorite policy is politically the most expedient as well.

(along with making sure their hormone level doesn't act as a PED)

That’s a “real world” line of argument is being taken by some people alright, same as a sports scientist who makes the point about 6’ 9” players in women’s basketball would be unfair, as though there aren’t 6’ 9” players in the WNBA, or bases their opinion on the idea that men are choosing to be women, that they’re prevented by law from taking sex hormones is the only reason it’s not happening at an earlier age. You’re accusing people of cheating, based upon your own personal beliefs. Don’t try and pass that off as a credible scientific argument.

Utter garbage.

Nobody is arguing any such thing.

You are, you are arguing it, whether it's hidden behind 10 random references to other things or not, you are either arguing that the female category shouldn't exist (because you say it's based on stereotypes) or that PED's should just be allowed whenever someone feels like the PED state represents their true state, hiding it behind walls of text doesn't hide it, it's either one or the other. This is the crux of your arguments and isn't representative of the topic being discussed in the OP where Thomas is specifically taking medicines to both represent their desired state and stay within the limits currently allowed for the female category for trans-women.

That’s an awful lot of words to accuse me of arguing that anyone should be able to cheat in competition.

You’re not one bit sorry, and I’m fine with myself in the mirror. You posted this earlier, and it doesn’t represent anything I’ve ever argued. It’s deliberately misleading -

So all sports people should be allowed to take PED? Or only some?

Os is this a vain attempt to re-classify what a PED is? (but again, only for some).

Should we return the trophies to Lance Armstrong and apologise?

None of this is my personal belief, I will follow the science.

The first claim - you’re aware that athletes are permitted to take drugs which are on a banned substances list provided they have a legitimate reason for doing so. An exemption exists in the rules already.

The second claim - you’re aware that I am not attempting to reclassify performance enhancing drugs. They are still classified as performance enhancing drugs.

The third point is in the form of a rhetorical question, attempting to categorise athletes who are transgender who are taking hormones, with cheaters, and they should be prohibited from competing with other athletes of the same gender when they are not the same sex classification.

The last claim - you’re following whatever you think has scientific merit in order to justify purposely putting anyone at a disadvantage in competition. If you can’t do that, then according to your personal beliefs, anyone who doesn’t volunteer to be disadvantaged, you can claim they have an advantage. It’s circular reasoning -

The problem with this issue of trans in sport is every sport is different. In terms of what personal physical attributes make a difference.

I know nothing about swimming, I can't even swim. But I would have thought that being taller would give you an advantage. Just like if a runner were twice the size of everyone else, (exaggerating to make the point) that would give one a very obvious advantage, and I can see how the same would apply to swimming.

This shows that men are on average taller than women.

The argument here is that some females are tall, the physical attributes that make the most difference tend to occur during puberty, larger lungs, hip more square, denser bones, some females will naturally have some of those characteristics but very few in such a way that makes sport an advantage for them (along with things like twitchy muscle fibres), so the very average trans woman will already be in the top few % of female characteristics which are advantageous to sport, reducing ongoing testosterone reduces some of that advantage, the jury is out on whether it is enough (and being trans has a set of disadvantages built in right now due to societal attitudes that may change over time, that makes it highly unlikely it will be very common and that athletes like Thomas will be an outlier for a number of years). I don't think the sports bodies will want to get it to the point where the single biggest advantage you can get in women's sports is to have been born male.

I don’t know where you get the impression that the burden of proof is on me to prove anything. You want to introduce the discrimination, the burden of proof is on you to prove it’s necessity. That’s the way equality legislation works, that’s the way the IOC policy works, that’s not the way organisations like the WA policy works, for now.

And if males who are not transgender were looking to participate in women’s sports, I’d agree there might be a legitimate justification for their exclusion at an individual level, as is permitted in accordance with existing equality legislation.

This is an interesting one and to me shows the potential unfairness in allowing biological men compete in women's sports. Bridges was an elite cyclist as a man, held a national record and most likely was training at a high intensity all through puberty. She wasn't a low level athlete before her transition. The athletic benefits that she accrued as a man are not going to be fully wiped out by undergoing testosterone treatment for a year. Being able to train at a higher intensity for such a long period of time is an advantage, hence the reason why banned athletes are still subject to drug testing if they wish to return after their ban. It will be interesting to see how she fairs against one of the best track cyclist of all time in Laura Trott if they indeed get to race each other.
