Seems to me that this applies to C1 as well, which I find more intriguing:

'Any symbol encountered in the Afterdeath Zone is sustained  
by people's belief in it....After millenia of being fed by a people's  
beliefs, the symbols are so powerful that no one alive could  
dissipate the energy contained in them.'

Same for this:

The idea that some symbols are living, means they are currently being maintained by
conscious thoughts of people (alive or dead) who believe in them.  
I'm not sure if they can be destroyed until the amount of destructive intent exceeds the amount of conscious intent keeping them active.  


That's true here too, though I would prefer to think of things being destroyed as more like sand castles being washed away by the tide (of positive energy) rather than thinking of trying to destroy things, though cute little boys tearing into my sandcastles might amuse rather than anger me....
