Imane Khelif is and has always been a biological female. She is not trans; she is a woman whose appearance is masculine by typical perceptions. She is a biological female competing in women's boxing.
AFAIK She is someone who has a DSD condition that gives her something close to a male puberty type advantage.
It’s not that she simply looks masculine or has higher than normal testosterone for a woman.
In a sport like boxing you can’t just aim to be maximally inclusive regarding things like this.
The average male punches at 167% of the average female, and some people with DSD are more in the male range, not the female. It genuinely can be a matter of life and death. This is why boxing has so many weight classes as mismatches in power are dangerous.
This is not simply US culture wars spilling over it is the view of many scientists who have looked at the evidence.
This is why governing bodies in combat and collision sports are much stricter than the IOC on this because they will get sued as they understand the science behind injuries.
In many sports it’s simply a question of inclusion v fairness with regard to DSD, in others it will reduce the number of deaths or life changing injuries.
Just because some bigots jump on the bandwagon, doesn’t mean the objection is simply irrational bigotry.
She is banned from competing in most other boxing events for scientific reasons that have nothing to do with right wing politics.
