“At present, the lede and the overall presentation state, in Wikipedia’s voice, that Israel is committing genocide, although that claim is highly contested,” Wales said. He added that a “neutral approach would begin with a formulation such as: ‘Multiple governments, NGOs, and legal bodies have described or rejected the characterization of Israel’s actions in Gaza as genocide.’” Currently, the article bases its position that a genocide exists on conclusions from United Nations investigations, the International Association of Genocide Scholars, and “multiple human rights groups,” among others.



So that means…
The moon landing is highly contested.
The shape of the Earth is highly contested.
Shit like this is why I had to leave Wikipedia. Trolls and paid shills can lock up any meaningful edit/argument forever if they want to. And the people running Wikipedia are no different.
fyi, both of your exemples would fall under wp:fringe
