Religion can cause violence, sure..
but refusing to acknowledge God causes the same thing.
The Nazis and the Communists disn't acknowledge Him. Look many died
under their hands?
'Spirituality' is too open, too general a category to speak of.
Religious people can also live meaningful lives. In fact,
Spirituality and Religion are not mutually exclusive, but must be
in balance with one another. Religion without Spirituality is plain
ritual, Spirituality without Religion is but empty talk.
