I tend to lean towards Maria's points. The letter/article tells us we should be prepared but says nothing about what "the prepared" should do about the "unprepared",,, such as the 20 million radicals, active in 82 countries, who have promised to kill-or-convert everyone else,,, and those "in-power" around the globe,,, and the traps of religious dogma around the globe...
What is the proposed process by which the prepared might enlighten the unprepared?
By what means shall we convince the unprepared that they are in fact "unprepared" and need to change? [They think we are the unprepared]
How might one tell the guy who is cutting off one's head that it is a mistake, that he should forgive and set one free, instead?
The children of those 20 million radicals are being taught to hate and kill at a very fast rate,,, how may we correct this problem without killing them faster that they can be trained???
Other than the underlying details, the premise of the article is quite sound in theory,,, maybe, if it could ever be implemented.
