Wikipedia is known for its references to sources and Wikidata is great at connecting these sources together. Particularly scholarly papers with a "DOI" may link to authors, cites works and works citing a paper. When a paper is of particular interest, you can expand the information in all these ways.
So I did not get into an argument about "water fluoridation", I included papers mentioned to Wikidata. I linked some papers with "water fluoridation" in its title to the subject. I attributed papers to authors including one by the Surgeon General of the United States..
Everything that was done on the subject is reflected in the Scholia for the subject. It suffices for me as my participation in an endless argument.
