Why Would a Holocaust Denier Live on the Upper West Side?

An amusing story in the Times today: A Holocaust denier inadvertently sends an e-mail blast filled with the typical dumbass denial horseshit to his kid's elementary school's parent listserv. Outrage ensues, but that is not what is interesting to me: According to the Times, the idiot, whose name is Michael Santomauro, lives on the Upper West Side. Now why would he do that? Is he some sort of masochist? Is he keeping the perfidious Jews under close observation? Has he looked into real estate opportunities in northern Idaho?
