Whether one admits it or not, the very reason racism still exists in Australia is because parents continue to put it in the minds of their young.

On the day Adam Goodes suffered his second racist slur in a matter of just less than a week, Daniel Motlop, a former North Melbourne and Port Adelaide footballer, tweeted his son, who was just a mere nine-year-old child, had already had his racist slur experience.

"My oldest son goes to school today and gets told by another kid he can't join in soccer because he's a Aboriginal. #grrr #truestory" and later posted "Truestory & was told 'because my dad is a police man and he locks Aboriginals up' ... What are some of you people teaching in your house"," Mr Motlop lashed out on Twitter on Wednesday, the very same day that Eddie McGuire, Collingwood club president, made the King Kong reference on Mr Goodes on Melbourne radio.

Racism Starts at Home Courtesy of the Parents

Still, Mr Motlop took pity on the offending child. "Not the kids fault, let's hope he learns from this," he told 3AW Radio on Friday morning.

"It's just a little bit disappointing (to see your son a little bit upset when he gets home) because you don't teach your kid ... how to react to these things because you don't expect them to happen these days."

Mr Motlop admitted he got angry, but trying to rein in his temper because "it's not the other kid's fault either."

"It's about what's coming out of the home and what he hears people talking about. It's about teaching that kid now and making sure he doesn't do it again and other kids not doing it as well."

Racism Part of the Game, But...

Unfortunately for Australian football, racist slurs are part and parcel of the game that players get fed into every week.

What happened to Mr Goodes on Friday night was "not a one-off incident, it happens way too often," James Brayshaw, president of the North Melbourne football club, told Nine Network's AFL Footy Show on Thursday night.

He said Australian football per se as a sport and as a group has been successful in stamping out racism against each other. But it was a different ballgame with the crowds.

"And I think Adam Goodes what he was doing last Friday was basically putting his hand up and saying: 'Enough. We shouldn't have to in the two hours we run out on an AFL field have to put up with that being said across the fence'," Mr Brayshaw said. "And I totally agree with him."

"I think it's a good stance and we as a code should support it."
