Disillusionment and a sense of isolation have been pinpointed as possible reasons for Australian Muslims joining the Islamic State.
During a discussion on SBS's Insight programme last night, 19-year-old Abu Bakr expressed support for the Islamic State and for Australians who chose to support its cause.
"They don't want to bring anything but justice," he said of the group.
When asked by host Jenny Brockie what justice was, he responded:
"Justice is giving, giving the right of the people, giving the rights to the people, feeding the people, sheltering the people, clothing the people."
But when the conversation later moved to talk of the government cancelling passports, Mr Bakr and his lawyer walked off the set.

The incident has sparked greater discussion about what drives some Australian Muslims to join the militant cause.
Brisbane man Yehya El-Kholed, who also appeared on last night's Insight, visits his Syrian family regularly.
He blamed the inflammatory rhetoric on social media, for the rise in Australian radicals.
"There are some sincere ones, people who want to help…" he said. "But the rest...it is like a popularity contest. Someone has gone; they all want to be like that person.
"You can see on Facebook and Twitter how they are promoting what they are doing."
Mehmet Ozalp, director of the Centre for Islamic Studies and Civilisation at Charles Sturt University, said feeling isolated and undervalued might drive some young Muslims to look overseas.
"Young Muslims - if they are unemployed, they are undervalued and not taken seriously - they may feel that by going into an overseas conflict where they feel that Muslims are suffering, they feel empowered," he said.
Radical groups are tapping into this disenchantment.
Muslim community leader Keysar Trad told SBS that radical groups were tapping into this disenchantment.
"They have succeeded in showing these people that they can belong there and we have to counter that," he said.
"We have to show these people – no, you don't belong there. This is not the place for you. You belong here. You are an Australian. We welcome you."
There is concern that radical prayer groups promoting the Islamic State are growing in parts of Sydney, including in Chris Bowen's constituency of McMahon which includes the Sydney suburbs of Fairfield and Blacktown.
The Opposition Treasury spokesman said Labor supported the government's condemnation of the groups.
"The international community condemns them, the Labor party condemns them and the government has our support for any action which reasonably deals with illegal support for what is a terrorist organisation," he said.
Muslim religious leaders are concerned by the number of young Australians fighting with the Islamic State.
The leader of the Australian National Imams Council, Grand Mufti Ibrahim Abu Mohamed, said in a statement that the men represented a small minority.
"Their misguided actions do not represent the overwhelming majority of Muslims who emulate the pure teachings of Islam such as justice, mercy and freedom," he said.
