Sir, I do not know you but I would like respond to your post if I may.
I do not know what you mean by 'THEY'. Who are 'THEY'?
I assume you mean terrorists, but what kind of terrorism means 'THEY'?
To me it is clearly a Muslim religeous ideology/theology that creates this 'Terrorism'.
So, shoudn't the Muslim Community Leaders identify the problem, stop being in denial, and suggest and offer their own community practical solutions, like reporting those observed in nefarious activities?
