I don’t think your article debunks the claims made by the UN Special Representative. From your linked article
The question has never been whether individual acts of sexual assault may have occurred on October 7. Rape is not uncommon in war, and there were also several hundred civilians who poured into Israel from Gaza that day in a “second wave,” contributing to and participating in the mayhem and violence. The central issue is whether the New York Times presented solid evidence to support its claim that there were newly reported details “establishing that the attacks against women were not isolated events but part of a broader pattern of gender-based violence on Oct. 7” — a claim stated in the headline that Hamas deliberately deployed sexual violence as a weapon of war.
NYT reported that the sexual violence was a systematic thing employed by Hamas as a tool while the UN report is about sexual violence having occurred there.
Also the report specifically mentions some of the same claims and says they’ve been disproven. And how they’ve done their own interviews and seen the photographic evidence for other things. So it doesn’t seem to be the same NYT thing you’re focused on.
