I wonder about the implications of being rational and secular. A present, my generation, me, mentality makes sense. Why have children? Why bother? I think religion can give a view that extends into the past, one’s ancestors, and the future, one’s posterity, and places oneself as an important link in a more important chain.
Another implication of being rational and secular may be the phenomenon of the bully. Why not pick on those weaker than yourself, if you get something from it? Why not snatch purses from little old ladies? Why not fear, and align yourself with, the big bad dude stronger yourself? It all makes sense.
Caring for the weak makes little sense devoid of some moral compass. I think history shows that compass was often religion, particularly Judeo-Christian religion. I’m not so sure about Islam.
Islam values alms to the poor. Unfortunately they don't value peace.
