There are many reasons, of which I will illustrate only a couple, but first, let us define what a Christian is. Many claim to be "Christian", but what exactly does that label entail? There are, essentially, two factors involved. The first, of a dogmatic nature, is a belief in God and immortality. Failing to belive in these two things, I think, effectively bars one from Christian ranks. The second is a belief in Jesus, which effectively bars Muslims and Jews from the halls of Christendom. As for a belief in religion, the only reason people accept the teachings of Christianity, or any other religion for that matter, are emotional, and rooted in fear. It is the terror of the unknown, in part, as well as the wish to ahve some sort of big brother to help one through all one's trails and tribulations. But fear is the root of it. Fear of the unkown, fear of the different, fear of death. Fear gives rise to cruelty, and it is no surprise then that religion and cruelty have gone hand in hand down through the centuries. I don't fear the unkown. I don't fear that which is different. I don't fear death. These things simply are, and to fear them give rise to unwarranted anxietywhich leads one to flee to the vicarious comfort of religion. I grew up, and left childish things behind me, not the least of which was religion. It serves many well, giving them comfort in their daily lives. But too many others use it for their own ends, which have nothing to do with the ideals of their religion. Instead the gratification of their own egos is their goal. Just watch the televised rants of any religious zealot for the proof of that .
