The act of splitting an [[idea]] or [[concept]] up into (more or less arbitrary) parts, and trying to enforce thought processes which are inhibiting attempts to allow these parts to mix together again.
The reason for this attempt of [[thought control]] is often to make it more easy to single out certain individuals, or to inhibit certain ideas.
one example is the idea of [[gender]], splitting gender into exclusive [[male]] and [[female]] treats, ignoring the fact that sometimes gender is not that easilly determined.
