Credit where credit's due.
Although some will doubtless carp and quibble...It didn't pretend that the attacks we've seen on the streets of London and Paris have nothing to do with Islam. It fully faced up to the fact that Islam is the problem, and that a radical reformation of Islam is needed. It showed us just how bad the situation really is. It showed the very ugly things influential British Muslims say behind closed doors. It confronted the 'grievance narrative' of non-violent Islamists that excuses the crimes of violent Islamists, including all that blaming of Western foreign policy. It showed how small the gap is between those two kinds of Islam. It confronted the Trojan Horse Affair and took on the 'Islamophobia' narrative that developed around it. It gave the lie to the 'Islamophobia' narrative as a whole. It showed the grievance mongers for what they are, and gave voice to those Muslims who want to fashion a genuinely moderate, reformed, pro-British Islam that none of us need fear (though how representative these voices are is a moot point). It even showed the most famous Charlie Hebdo cartoon of Mohammad, holding it in focus for several seconds..
It was a very big step forward for the BBC, broadcast at peak viewing time on BBC One. Please watch it if you can.
