Night: Here's your cite, which actually addresses several of your wishes: WP Biographies of Living Persons. You should look especially to: "Using the subject as a self-published source" - it states that "the article is not based primarily on such sources.". Thirteen of your eighteen source references are to Pedro and Me, or Winick's personal sites (yes, IMDB counts). For example, you cite the book as the reason for keeping in the discussion of Rainey, while I repeat-it's an isolated, non-turning-point event in his life. It is appropriate for the Real World page, perhaps, but here it's a little off-topic. You might as well put in the name of a flavor of ice cream he doesn't like, or that someone was mean to him in middle school. It's just not important enough for what should be a short bio. And a link to Zamora's bio can cover his illness, a mention that he had HIV/AIDS and was ill covers him quite nicelythere's no need to go into it, except for the impact it had on Winick. I'm just trying to get the article back on track as a one-topic writing hereI'm not "accusing" you of anything. 

To answer your direct question, see the heading "Presumption in Favor of Privacy", under "Privacy of Birthdays" on the same page-it may be published elsewhere, but I don't know that he's quite notable enough to justify keeping the full date-where's the harm in only noting the year? It seems a fairly harmless, sensible change to me. 

Also, can someone who is more familiar with the subject add back a criticisms section? As there are two of us, at least, that came to WP solely to find out what the controversy surrounding him might be, can someone add this information? I'm still in the dark. )
