Off topic: When I first saw the title I thought this would be more metaphorical representing contrasting human personalities and paranoia in which the vast number of people expressing different opinions make you seem an outcast and/or a target....
On topic: however after looking at the main topic, according to Drakes Equation, in which we take the approximate number of galaxies, filter it so all that remains are the existing solar systems, filtered to all of those with atmospheric planets, then to capable of supporting life; the original number was innumerably large, and the end result not so, however it leads us to presume that there are at least hundreds of thousands of intelligent life forces existing besides ours.
However due to the possible dispersal patterns, these are all estimated to be on average several hundred light-years away from each other. To explain in a simpler fashion, if one of these life bearing planets had a telescope that could see the distance, the reflected light that they would perceive of our planet, would be several centuries reflected and thus they would see the human race during the middle ages and not at the present state... (maybe that wasn't simplified but oh well).
