The 34-year-old suggested yesterday that he is not confident that the campaign are doing all that they can to eradicate discrimination from the game.
"I support him 100%," Brown told BBC Radio Five Live. "I've had this stance since an incident when I was playing for Gillingham against Chesterfield a few years ago.
"After the lack of support I had from 'Kick It Out' and the FA, I said I would never support them because I feel they don't want to help players in the lower leagues. We need to feel confident in terms of the people who are dealing with these matters. We don't feel that."
Meanwhile, 'Kick It Out' have defended their work following the recent controversy.
