WP:NPOV - " neutral point of view (NPOV), which means representing fairly, proportionately, and, as far as possible, without editorial bias, all of the significant views that have been published by reliable sources on a topic."
WP:WEIGHT - "Neutrality requires that each article or other page in the mainspace fairly represent all significant viewpoints that have been published by reliable sources, in proportion to the prominence of each viewpoint in the published, reliable sources."
"Undue weight can be given in several ways, including but not limited to depth of detail, quantity of text, prominence of placement, and juxtaposition of statements."
If the prevailing argument and your counter-arguments are due to some division of humanity (e.g. by nationality, religion, education, etc.) then try to find a valid source that indicates this and add this information to the article.
In particular, this places on the majority the burden of providing sourced information that clearly identifies what the opposing majority opinion is (assuming that there even is disagreement), which may be useful if, for instance, the article is already presenting a minority view as if it was the only/majority view.
Policies to cite if someone adds false/non-neutral statements or removes one of your properly sourced statements:
WP:PROVEIT - The burden of evidence lies with the editor who adds or restores material.
WP:BURDEN - "The burden to demonstrate verifiability lies with the editor who adds or restores material, and is satisfied by providing a citation to a reliable source that directly supports the contribution."
It also notes that: "Once an editor has provided any source that he or she believes, in good faith, to be sufficient, then any editor who later removes the material has an obligation to articulate specific problems that would justify its exclusion from Wikipedia (e.g., undue emphasis on a minor point, unencyclopedic content, etc.). All editors are then expected to help achieve consensus, and any problems with the text or sourcing should be fixed before the material is added back."
"While information must be verifiable in order to be included in an article, this does not mean that all verifiable information must be included in an article."
"Consensus may determine that certain information does not improve an article, and that it should be omitted or presented instead in a different article."
"surprising or apparently important claims not covered by multiple mainstream sources;"
"challenged claims that are supported purely by primary or self-published sources or those with an apparent conflict of interest;"
"claims that are contradicted by the prevailing view within the relevant community, or that would significantly alter mainstream assumptions, especially in science, medicine, history, politics, and biographies of living people."
{{as of}} when the statement's validity is someone dependent upon time
Ex: {{as of|year|month|day}} or {{as of|year}} or {{as of|{{CURRENTYEAR}}|{{CURRENTMONTH}}}} (gives: As of September 2024[update]) or {{xt|{{as of|{{CURRENTYEAR}}|{{CURRENTMONTH}}}}}} (gives: As of September 2024[update])
