I would like to quote what Graham E. Fuller wrote in his book: "A World Without Islam". He wrote:
"Religion is an exceptionally powerful human force.  It deals with gut issues such as meaning of life,
death, war, moral behaviour, community, and sexuality.  It acts on the individual human psyche,
psychology and behaviour.  Its impact is rarely limited to the individual alone, but acts upon
an enitre community of believers who take part in community acts of worship.  At the same time,
religion helps define and strengthen the community of like-minded believers."

From my point of view, when I see some Muslims are easily provoked into violence at the slightest
negative remarks on the religion, I have my qualm on the "goodness" of religion.

Former Prime Minister of India, Jawaharlal Nehru lamented: "There is much tomfoolery
in the practice of religion".

Jonathan Swift, English writer (1667 - 1745) wrote:  We have enough religion to make
us hate, but not enough to make us love one another.

Apparently, this is still true today.
