Lots of PP are saying this is totally unfair, the women they are fighting don't stand a chance, and this is actually dangerous.
But these two people regularly lose against women.
According to their wikipedia pages, Imane Khelif has won 9 and lost 5, Lin Yu-ting has won 19 and lost 5. Isn't this around the level you'd expect from an olympic level competitor?
Do you expect these two to both easily take gold?
And boxing is done by weight category, so these two must weigh very similar to their competitors. Imane Khelif is light welterweight and Lin Yu-ting featherweight.
You may well think that these two have some unfair advantage, that maybe they can punch harder, or move faster than the people they are fighting?
But they definitely can't punch as hard women in the upper weight categories, and therefore is must among the less dangerous women's boxing fighters.
So I think it IS unreasonable to be scared for their opponents.
