I agree that having a correct map of reality is needed if you care about arriving at some (I hate this word) "materialist" goal, but not everyone can live in a more liberal area of the US/world. Areas where not fitting into the local community creates more burdens than necessary.

For example, when I was in the military, I identified as an atheist pretty openly, barely concealing my contempt for religion. One of my last Enlisted Performance Reports, my supervisor said I would do better if I were a Christian. I wasn't sure if that was a threat, or him implying that I was immoral and thus not quite a fit in the military community, but nevertheless I was penalized (in his eyes) for not being religious.

There's the map of reality, the map of the physical roads and buildings, but there's also the map of human interactions. One can signal consciously, but what I gather is that most people signal unconsciously and then generate a cached version of themselves that eventually becomes the real them (belief in belief and all that). While I might say I had an accurate map of reality when I was in the military, I didn't have, nor did I want to even accept, that there was another map of social situations that would also have helped me reach my goals more efficiently if I had an accurate map of it.
