This is the farcical state we've got ourselves into as a society. Someone, born physically as a man (note I'm NOT referring to what's going on mentally) decides to change gender. They're a professional swimmer. So they're now allowed to participate in female swimming events. Ok, so as part of their transition they take meds etc to reduce their manliness, however are we seriously saying all their male attributes are gone, especially around physical capability?
Result? They start posting amazing times and many female competitors (who were born female) will never in a month of Sunday's be able to compete with them. Yes the very top tier might give them a run for their money, but many won't have a chance, no matter how hard they train etc. A bit like going up against someone who's using illegal substances.
What's even more farcical is, if you try to question this, you get labelled an 'ist' and are shut down by many quarters of society.
We're getting ourselves into a right tangle around all of this, trans women attacking from birth women in prison etc etc.
Why not create a trans level in athletics? Oh no, we can't do that, that's against their human rights. Solution? Let's shoe-horn them into from birth male and female events. Yeah, great solution ...
