And it's not just Muslims who need to start them.
Many of us go through periods of radicalisation – spotting when this is a danger rather than over-reacting is the key.
The moderate majority of Muslims need to claim Islam as a religion of peace to counter the loud voices of extremists.
A struggle is underway for the heart and soul of Islam. Moderate Muslims need to engage in the contest to ensure their view of Islam is the one that prevails.
One needs to understand the differences in their Islamic movements to make sense of events over recent decades in Egypt and Iran.
People sometimes overlook their profound differences if social forces unite them in a common, often ill-defined desire. Hostility to Muslims is creating an imagined solidarity that Islamists can exploit.
Religions can promote division and inequality in our societies.
Fundamentalists become warriors with a simple message of salvation that is found in a naïve and literal interpretation of ancient, sacred texts.
Islamic State leader Abu Bakr al-Baghdadi, as self-declared caliph, seeks to exploit the historical resonance of the caliphate for a brutal present-day cause.
The Caliphate has inspired disputes among Muslims for centuries, but attempts at revival in modern times are unlikely to succeed. Most of the world's Muslims would not accept its authority over them.
Schools should teach students about peace and pluralism to reduce radicalisation, not necessarily about every world conflict and religion. Australian teen Jake Bilardi with Islamic State fighters.
Introducing new curriculum requirements to teach young people about specific issues or requiring teachers to look out for signs of radicalisation are just as likely to have little or no impact if not supported by evidence.
No society is immune from the rise of ‘us and them’ intolerance expressed through anger and a desire for brutal revenge.

Zaky Mallah argued that the government’s policies play into the hands of ‘recruitment propaganda’ designed to appeal to alienated young Muslims.
It is important that we do not entirely dismiss Zaky Mallah's comments on Q&A. He sheds light on a seductive mechanism for young Muslims that is real.
