Eddie, //there is no reason to suggest it was inspired by Islamic State.//
Yes, there is. Read my link from the BBC.
//The attacker made no attempt to target Muslims or Non Muslims//
Why would he? Muslims died on 9/11 and on 7/7, and in just about every atrocity ever committed by Islamists. Muslim lives are as expendable as any other for ‘the cause’. That's why these madmen have no hesitation in blowing themselves to smithereens. You too need to learn about Islam.
ummmm, I do have Muslim friends – and no I don’t think they want to kill me. If, however, I were to be killed, they woud be aware that their literature condones it - and they wouldn't take to the streets in protest.
