Why do people ume that everyone else out there shares in some sort of a similar collective consciousness?

Well I agree with that, its just that people tend to be ignorant and react on instinct and judgment rather than rational sense... Its hard for some to use common sense and to just accept things the way they are because they are not used to it. Its the way it is, sometimes things are the way they are, and whether we like or not we just got to live with it. We can chose to not be with it and not against it but we have to come to terms and respect it. Because the damage that's being done here is not them but us. I don't know if that's the answer your looking for but that's all I got dude.
