That makes plenty of sense, Eugine_Nier, but the premise of this whole little exchange (admittedly, several layers up in the comment thread) was that at least some people do care enough to try to save their neighbors, and only refrain because of social norms against being annoyingly evangelical.

But it’s worth wondering, when we consider a society which upholds a free market of ideas which compete on their relative strength, whether we’ve taken adequate precautions against the sheer annoyingness of a society where the taboo on actually trying to convince others of one’s beliefs has been lifted.
