While I appreciate the author's sentiments and agree absolutely that the Muslim community needs to step up this article continues to tiptoe around a few inconvenient issues. 
First of all Ms. Khan slides in that tiresome idea that these murders are about revenge for the misdeeds  of the West. 
Second of all,  even though Salman Abedi certainly associated with some nasty jihadists and may have come under their spell his family have been actively involved in the Islamic fight in Libya for years. 
Abedi senior left Libya to escape Qadaffi and returned to join the fight as soon as the regime change started. 
He encouraged his sons to do the same. 
Britain wasn't a new home - it was a hideout. 
Lastly. 
The Muslim community will have to use stronger and louder language to rid themselves - and us - of the extremist Islamic spectre. 
In the secular West it is religion that must ALWAYS adapt.
Learn it.
Live it.
