I started wondering whether my post had been a bit too serious,but re-reading this thread in daylight it looks as if some people did take the topic deadly seriously (e.g. drowning, the deaths of loved ones) while other suggestions were surely tongue-in-cheek joking. (Does anybody really go in fear of meeting a zombie(!)) or actually worry about aliens ( alien beings from Outer Space, that is, not the ones from other countries who are so inconsiderate as to not look or sound just like us)? But I do genuinely fear, and there are enough cases to show that my fear is not paranoia, that when I am in some crowded place among people I don't know, even our local supermarket for instance, my wife or I could do or say something, even if it is totally non-political and simply misunderstood, which will trigger a reaction from one of the people/vicious fanatics who, as I said, are ready and even eager to use violence against the "other", even to the point of exercising their damned "Second Amendment Rights". This kind of thing has happened, and it is not paranoid to visualize it increasing.
