In this specific case the attacker wasn't Asian and you may not have benefited from the defence of treating all Asians with suspicion.
However recent photos show him sporting a full beard so perhaps we need to view all bearded men with suspicion.
ISIL or whatever they are presently called will be very pleased to know that we are getting to a stage where all Asians/ Muslims are viewed with suspicion. It means they are one step further on the path of seperatism and using their 'victim' ploy they can then appeal to all Muslims to see that they are under threat and to join ISILs ranks either directly or through tacit support.
Its a sick world and its going to get much worse before it gets better.
