I agree it is unfair but people are making a bigger deal of this than it deserves. There are nut jobs claiming this woman was assaulted by a man.
1. They are both women with vaginas.
2. She's a boxer. It's her job to get punched.
3. Getting punched hard by a boxer is not assault. It's part of your fucking job.
4. Lots of women have fight and beaten Imane Khelif. Only one of them has cried after losing.
Ideally, I agree that we should have a separate class for inter sex people in sports, or decide that they go in the Men's category. But for many reasons, that would be impractical.
