Maybe it is not the "building your own reality" which is the problem but the idea of nation states in which you have to be in a particular reality without a say

Maybe it is not the "building your own reality" which is the problem but the idea of nation states in which you have to be in a particular reality without a say. It is probably better for humans to live in smaller structures over which they have more control. Concerning the division between liberals and concervatives in the States I think it is interesting to mention that Theodore Kaczynsky has written that the opposing evolution of these two systems(with the money a power they have) may lead to a larger conflict than other systems like Islam. He calls them self-propagating systems which are somewhat organisms on a higher level controlling more or less nodes, which are human brains(and machines nowadays).
