It's also weird to see Australia called an apartheid regime. For all the terrible things done to the indigenous here, things weren't arranged as in South Africa. The US treated it's indigenous in a similar manner to Australia (though not quite as bad), and had legal segregation in the South (cue photo of water fountains), but we wouldn't characterise the US as an apartheid regime. Apartheid was a political system limiting people of colour in order to maintain power in the hands of minority whites - both Australia and the US had significant white majorities, with whites in easy control of the political machine.
Finally, the article is also wrong to call Norman the biggest hero on the podium. Norman should be lauded for his actions, but he was still doing 'support' - the main act was done by Smith and Carlos. Had they not acted, there would be no notable photo.
