Victims of forced adoption say they are disgusted at the actions of Simon Crean after he triggered yesterday's Labor leadership spill.
More than 800 people were in the Great Hall of Parliament House yesterday to hear Prime Minister Julia Gillard during the 1950s and 1970s.
The president of Adoption Loss Adult Support Australia, Patricia Large, was among them.
She says Mr Crean and Labor Party infighting ruined what should have been a healing day.
"I'm really disgusted with what happened," she said.
"They could at least have let us have the day to celebrate everything that had happened to us because it was history, it was monumental, and I think the behaviour of all of the politicians is absolutely disgusting and disgraceful.
"It overrode our apology.
"It made us feel like we were worthless then, and we were worthless yesterday."
Ms Large says many victims are angry and disgusted.
"Why did we put ourselves out so much for everybody to get to Canberra, to have such a beautiful day with what Julia said, and then to have it all crash to the ground?" she said.
"Before we had even left the tent from having our meals, we were hearing that they were toppling Julia."
Ms Large says Mr Crean should have kept quiet.
"He should have done nothing, he should have given us the dignity and respect that we deserved on that day," she said.
She says Ms Gillard and Mr Crean should apologise.
"Julia Gillard should now come out and say I'm deeply sorry for what happened in the Labor Party on your day, on your important day," she said.
She says Kevin Rudd promised her a week ago that he would not challenge Ms Gillard on the day of the apology.
"I knew that Kevin Rudd would not do anything on this day to us deliberately," she said.
"He promised me a week before that there was no way he would challenge Julia, that there was no way he would upset anything to do with the Labor Party because as far as he saw it, Kevin said it was our day to celebrate, it was our day to take in the apology and nothing should override it."
Mr Crean says it is unfortunate his call for the spill clashed with yesterday's apology, but his actions were necessary.
"All of those people who have suffered in these circumstances, I hope that yesterday did help them," he said.
"I am sorry for the rather frenetic pace that was around it, but that couldn't be helped."
