i think saying that all people with faith or religion are deluded is unreasonable
i have a faith and i believe to a certain extent, although am not 100 % sure.. i did read the god delusion, and found i really hardgoing but thought provoking.
i believe there is something more out there than people, call it god or a higher power, or mother nature or wahtever..
we all control ourselves to some extent, whether it be via following hte natural law, religion, other faith /belief etc. etc
there has to be some level of control /morality within society
i think a good way to live , generally is, do unto others as you would done utno yourself
can't go far wrong with that
