I see it somewhat differently. I think the point here is that, taking into account all 2.7 million Muslims in Britain, there are more Muslims who are willing to join a murderous fascist organisation than there are Muslims willing to join the Armed Forces of the island which is their home (and, for many, their birthplace).
I find it troubling that there are so few Muslims in our Armed Forces, and that
must speak to and reflect on broader attitudes in the Muslim community. I would hope many more Muslims would feel that the British Army is
their army too. That it protects
all our people. I am concerned when some Muslims feel that their politico-religious affiliations to Muslims in other parts of the world overrides their connection to the island-state which is their home
You are undoubtedly correct. Many of the Brits in the ISIS ranks are deeply troubled individuals, and you are right to point out that it would be an easy sell to say to these people who have never felt special in their lives, that they will be great warriors on a grand adventure to create a utopia.
There are many intersectional issues there. Some of it relates to class and socio-economic background (almost all people from underclass and marginalised backgrounds distrust the police and many Muslims fit into that socio-economic category).
However, it's also fair to say that many White British / Anglo British people from the working and underclass end up as squaddies and join the forces. But that's far too big an issue for me to tackle on this thread, I happily throw up my hands there and say, another time.
Well it is public knowledge that there are about 600 Muslims in the UK Armed Forces. The figure bandied about is that there are 500 British Muslims in ISIS. So we know that whatever the exact figures, let's say conservatively that there are about as many British Muslims in ISIS as in the Armed Forces.
