The Australian radio presenter, who was reprimanded during last year's Winter Olympics for making seemingly homophobic comments about a gay figure skater, recently referred to a Sydney suburb as "the land of the falafel".
On his breakfast show, McGuire said to Greater Western Sydney Giants coach Kevin Sheedy: "I've just put a team together of your 17-year-olds who'll be sick of living up in the land of the falafel in western Sydney."
Islamic Relations forum director Kuranda Seyit told the ABC: "He's a mature man, a leader of a sporting club and a TV personality.
"He has a lot more weight and what he says influences a lot of people. I think that for him to flippantly throw around such a comment is actually quite irresponsible."
