The contents of the Israeli Association of Rape Crisis Center’s paper alleging “systematic” Hamas rape derive largely from discredited second-hand testimonies and debunked media reports. Among its most heavily cited sources is a dubious NY Times article that triggered a staff revolt at the paper.
Considering the fact that Israel has killed more journalists, more healthcare workers, more aid workers, and more children during this conflict than Russia has in Ukraine I would say it is definitely worse. The invasion of Ukraine is wrong, but Gaza has become the world capital of war crimes.
Just compare the civilian deaths: UN Human Rights Monitoring Mission in Ukraine has verified 30,457 civilian casualties since 24 February 2022, including 10,582 killed and 19,875 injured.
