I think i like Poster: i like belligerentyouth's --'Objectification' is so simple, I guess that's right.

i think that is the psycological term for it.. psychotics tend to do it.. they are unable to see others as human, they objectify them..

societies do it too, if you make the other in your society an object-- not quite a real human, then, you don't feel guilty making them into slaves, or killing them, or starving them.. (pick a country-- US, Germany, England (viz Irish)) and with 10 seconds more time, i could think of a dozen other countries that have done it.
