If this Algerian boxer was born male, then it's whole another thing in comparison, much less complicated and should be excluded due to undeniable huge advantage.
From what I understand she wasn't necessarily born '
male'.
Let me be very frank: I think any trans athlete born a biological male should be banned from female sports on a competitive level, even if I have no ill will towards them. The advantages are numerous and it's never a fair fight. When it comes to trans athletes the answer is easy.
DSD is not really as simple as XY = male and XX = female though. One of the more famous examples is androgen insensitivity syndrome. These are people born with XY chromosomes, but their bodies do not respond to androgens on a cellular level. From the outside they can look and function completely like women (albeit they are not fertile obviously). It would be really difficult to categorise them as strictly male. And frankly their condition is probably not helpful in sports.
In this case it would appear though that there is an obvious benefit from a competive point of view and personally I would exclude her.
But even so this debate is never as simple a line as people say. For example we have doping tests that measure the amount of red blood cells and we say that if you have more, you must be cheating. But humans evolve. What if someone evolves to be able to hold more red blood cells? We don't accuse Bolt of cheating for having better achilles tendons. And even worse: sprinters are flagged for false starts when they react '
more quickly than humanly possible'. Who is to determine what is humanly possible? I'm definitely not capable of running a 9.58 100m and I'm human.
