Both Palm and vice-chairwoman Teres Lindberg came in for some poignant criticism during Saturday's meeting with the chair of meeting forced to intervene to restore order.
Much of the criticism was directed at the closed process used to nominate Omar Mustafa to the party's national executive board.
One member pointed out that Palm and Mustafa had given different versions as to why he was forced to resign only six days after his election, expressing regret if the the decision was made due to media pressure.
Palm has argued that it was due to Mustafa not having taken a strong enough stand against the extremist views held by some speakers invited to Islamic Association events.
Mustafa meanwhile claimed in a well-attended press conference on Tuesday that the party had buckled in the face of a media circus, which it deemed to be Islamophobic.
The matter continues to divide the Social Democrats with former justice minister Thomas Bodström the latest senior figure to criticise the party, calling it undemocratic and outdated.
