Because this is a politicized topic no one uses common sense, they come in with preconceived notions and aim to find supporting facts for their predetermined opinions.
This issue is actually quite nuanced. The fighter has an intersex disorder which makes their sex ambiguous to anyone that doesn’t have access to their medical record, and she has been disqualified from competing in past events due to failing female tests, Olympics is one of the few places to allow her to compete.
I think calling an intersex person who claims to be a woman a man is wrong, even if they have psychical traits of a male (XY chromosome & higher testosterone).
However – in terms of competing, we segregate combat sports by sex for a reason, so if you have the physical advantages of a male you should not compete. It’s not a matter of just competitive integrity, but safety. Fighting is always dangerous, but men or anyone with the physiology of a male fighting women is extremely dangerous. In grappling maybe not, but in a combat sport with striking yes. We have to table our feelings and see that when determining if someone should compete.
But I think the rhetoric around the issue is gross. I don’t think theirs malice persay, rather the individual is intersex, has masculine traits and is really strong so people falsely presumed they were trans. It’s a reasonable assumption to make as being intersex is incredibly rare but nonetheless they should’ve verified this information before making public statements, as I try to do.
