Di Canio has been forced to deny accusations that he is a racist since taking charge at the Stadium of Light, following quotes attributed to the Italian from an interview in 2005.
"I have clearly stated that I do not wish to speak about matters other than football, however, I have been deeply hurt by the attacks on the football club," he told the club's official website.
"This is a historic, proud and ethical club and to read and hear some of the vicious and personal accusations is painful. I am an honest man, my values and principles come from my family and my upbringing.
"I feel that I should not have to continually justify myself to people who do not understand this, however I will say one thing only - I am not the man that some people like to portray."
"I am not political, I do not affiliate myself to any organisation, I am not a racist and I do not support the ideology of fascism. I respect everyone. I am a football man and this and my family are my focus. Now I will speak only of football."
Di Canio's first match in charge is away to Chelsea at the weekend.
