Wikipedia:WikiPurpose

Wikipedia has a lofty goal: a comprehensive collection of all of the knowledge in the world.

The purpose of Wikipedia is to document the sum total of human knowledge as it's found in reliable sources. Therefore, our primary function is inclusionist by nature. We first seek to build and include, not destroy and delete. Content submitted in good faith should be viewed with an eye toward improvement and inclusion, saving deletion as a last resort.

Wikipedia has a legitimate and necessary deletion policy, but that does not mean that all proposals to delete an article, aka an AfD, are legitimate. Therefore, editors should ignore all problems with the article and ask themselves only one question: "Does this article pass our general notability guideline (GNG)?" If so, !vote Keep, as that is the only relevant question at an AfD. If the article appears to fail GNG, then ask: "Can it be rescued by finding more RS to establish its notability or otherwise satisfy GNG?" If so, then advocate for that before finally !voting Delete.

All other concerns and problems with the article are covered by the editing policy's enjoinment to preserve (by fixing and improving) all the imperfect and incomplete content added in good faith. Honor the efforts of other editors. Wikipedia is inclusionist by nature, so editors' first impulse should be to fix, improve, and include.
