The Antisocial Socialist

To be specific, some primitivists object to them. Mostly Zerzan, and mostly as a thought experiment, because arguably even other primates have some symbolic thought. To not have these things, we probably really couldn't even be called humans--and how one would get rid of them is never addressed.

However, the reason they object to them is for the same reason they object to (insert a technology here)--they think it's a slippery slope. The ideology holds that technology and civilization is a totality created by mediation between humanity (the animal) and it's environment. They also hold that our social relationships (statism, patriarchy, stratification, exploitation) are inherent to our material culture and in particular the existence of a surplus. They are opposed to surplus. It is with surplus that one finds time to do things other than only surviving.

You probably should ask a primitivist if you want to know more. It's an ideology I only have score for. If I thought it had a shred of a chance of implementation in even a minor way, I'd have to be hostile to it's proponents. Fortunately for everyone involved--I simply can't take them seriously. I think noone else should either.
