Wikipedia policy is verifiability and giving the reader a first step. Truth is something that the reader decide for themselves. Wikipedia are neither the enemy nor a friend for regimes or political movements.

It is not the role of Wikipedia to authoritative say if the war in Gaza is an genocide. Their role is to say what reliable source has reported, which in this case has so much reliable sources talking about it that there is a dedicated article about just it.

There more reliable sources are talking about a subject, and the more the subject gain notability, the more likely it will be included in Wikipedia. Editors can apply some common sense, but they are not the arbiters of truth, nor should they ever be seen as such. If a readers want simple and single truths that they can believe in then they are better served by whichever news papers that can cater to their particular world views.
