If he is mentally in a really bad place (and this is not just media/AFL spin) stop booing.
There's reports that Goodes is considering walking away from the game and the matter is affecting his mental state. I think it's now clearly gone beyond the intent of booing whether racist or not. We are dealing with a fellow human being who has reached breaking point. I think the entire AFL public community should back off and let him play football. I'm no fan of his but I don't want to see this end badly either.
