Steffensen on Friday threatened to sit out the Games and not be part of the 4x400m men's relay in protest at teenager Steve Solomon receiving an individual 400m spot.
The controversial runner went one step further in an incredible tirade on Channel 9 on Saturday morning, saying he has been racially vilified by AA.
"I don't think it helps the legitimacy of our sport or the selection criteria, and I think it only makes our sport look stupid," he said of AA's decision to name the 19-year-old Solomon ahead of him for the one-lap race.
"The rules and the goalposts are getting shifted. Now they're going to pick who they want to put in the team.
"I've put up with being racially vilified by this federation, being discriminated against on many teams.
"...You think I waste my time running at training for fun? For this?
"No, they can have athletics. I don't need to do this no more."
Steffensen didn't back down when asked about AA's alleged racism.
"Read between the lines. I don't really have to explain anything to you," he said.
"You know it would help if I was a different colour.
"A lot of my decisions with my federation would be totally different.
"But I've never brought that up. I've always kept quiet on that. Because people aren't really going to want to hear that sort of stuff.
