Date of Birth 

Without much trouble I found a half dozen uses of the LDS Family Search genealogy database in longstanding Wikipedia entries. You're misinterpreting https://en.wikipedia.org/wiki/Wikipedia:Biographies_of_living_persons#Avoid_misuse_of_primary_sources  It would be applicable if I went to New York and accessed primary birth records. The LDS website uses a third party aggregator as described at the reference. In addition when you deleted the date of birth this time, you deleted the place of birth.
