Zombies addressing the importance of individuality

I believe that zombie ideas stem more than just from the fear of government in American culture, or the fear of industry. It seems that even in its roots in Haitian culture with the slave trade historical background even emphasizes the point I'm about to make. It seems that zombie ideas stem from the fear of losing individuality. Zombies are mindless and act only on instinct, on a one track mind and cannot think beyond this, while the humans left during a "zombie apocalypse" are forced to act to survive, which brings out the animal in them and makes them willing to do anything to progress in life. This also could be perceived as them not really turning animalistic in defense, but that they could possibly be altering their form of reality to match and deal with the situation at present. They cannot deny what is going around them, so they adapt, and maybe are more human than we give them credit for because they are able to do this. Needless to say, the zombie idea definitely plays on the fear of losing individuality, whether its with the slave trade or with a powerful government looming over nd making decisions for a large group of people who aren't individual anymore, but merely an unrecognizable face.
