::::If you want to add a section about the controversy about Track Palin, please go ahead and do so.  Otherwise, please stop deleting sourced material on the basis of spurious arguments.  WP:DOB simply is not an issue here.  The information is simply information.  It is a controversy if you want to make it a controversy; do so if you think it would enhance the value of the article. 
 ::::You mention: "If the subject complains about the inclusion of the date of birth"  as far as I know, this is not an issue.  If Track Palin has complained about the inclusion of his date of birth, this would be relevant please cite this complaint can be found.  If not, the argument is irrelevant.
