I suppose it got deleted because there's a difference between pointing out biological reality ('Niyonsaba has internal testes') and being cruel to someone who was incorrectly recorded as female at birth through no fault of their own ('there's a dude in the race!').
However, the race was a farce and Coe needs to address this ASAP. These athletes were banned from 400 to the mile in the hope that the problem would go away. Evidently, it hasn't. The difference in body shape alone is clear as day whilst watching, even if you ignore the ridiculous turn of speed at the end of the race that left world class women in the dust.
