I just read through it. The normalization of taboo is an interesting one for sure.

Without any normalization of taboo it seems society would be at a standstill, but with to much the fabric of civilization begins to unravel.

For me the main difference here is how natural the information distribution is. If it's heavily top down, as it is with legacy media, ideas which are commonly unaccepted may be perceived as normal. An illusion of consensus.

With a more peer to peer way of communicating I would guess that kind of manipulation would be more difficult.

What taboos came to mind for you when you thought about it?
