Frank Borzellieri, 48, was quietly promoted to principal of Our Lady of Mount Carmel School two years ago - despite a history of controversial writings and campaigns, including a push to ban a biography on the Rev. Martin Luther King Jr.
In 2004, Borzellieri wrote the book 'Don't Take It Personally: Race, Immigration, Crime and Other Heresies,' in which he declares 'diversity is a weakness' and says the rising black and Hispanic populations in America will lead to the 'New Dark Age.'
He has also written frequently for the white supremacist publication American Renaissance, with which he is still 'intimately involved,' the non-profit Southern Poverty Law Center says.
