Are you suggesting we embrace them whilst they stick a knife in your back? The killings on the bridge yesterday were completely indiscriminate, the person concerned was probably seeking martyrdom and looking forward to all the trappings that come with such immortality. But I agree there are plenty of people out there willing to stir up hatred among us and they need to be weeded out of society and if they come from overseas returned to their homelands or place of cultural identity where they can and will fight amongst themselves.
