There is much good to be derived from religious practices, where humility and love, plus acceptance and respect for others remain a central theme. Where this is the case, religions have no doubt done a great deal to contribute positive benefits to our civilized society. The problem arises, however, when religions take an imperialistic approach to all of humanity.
I do not claim to be a religious scholar, and frankly I wouldn’t want to be. Instead, I speak from my own observations and personal experiences. I would suggest that something becomes a religion any time there is an attempt to dogmatize a belief as the ultimate rendition of the truth, whether that something is related to lifestyle or spirituality. A key ingredient in this dogmatization is to deem everyone else on Earth to be wrong.
