Once you subscribe to an ideological dogma as a solution to certain grievances, it then frames your mindset.

Preying on the grievances of disaffected young men is the bedrock of Islamism.

I had the assassins of the former president of Egypt, the leader of the Muslim Brotherhood was with me in prison, the leaders of my own former group Hizb ut-Tahrir were with me in prison and so by the time I was released at the age of 28, I wasn't the man who went in at 24.

If we are true small 'l' liberals, it's our job to seek out feminist Muslims, ex-Muslims, liberal Muslims, dissenting voices within Muslim communities, gay Muslims - we should promote those voices and in doing so, we demonstrate Islam is not a monolith, Muslims are not homogenous, and that Muslims are truly internally diverse.

I can now say that the more I learnt about Islam, the more tolerant I became.

Within our lifetime, we can remember a time when Islamism wasn't the dominant form of discourse or the aim should be to minimise the absolutists within any religious community and contain them.

In prison I had the opportunity to debate and discuss people that had subscribed to all forms of Islamism.
