IMO he and his family are fair game.
Oh i agree with you. Serious writers actually do exhaustive research and interview hundreds of their subjects peers; both friends and detractors...they don't stalk their subjects. And they will politely ask the subject for an exclusive interview., which they don't always get. Activist writers try to become part of the story themselves so they'll have something controversial to write about. There is no way a conservative public figure like Sarah Palin would give an interview/actual quotes directly to a democrat activist stalker...other than to say "Stay the hell away from my family".
"IMO he and his family are fair game."
I agree again. The problem there is nobody would buy a book about Mr. McGinnis.
