It seems like we can categorize folks into boxes so we can decide what purpose religion serves. A) We have the folks who need it and should participate in it. These are the folks like my wife. They have issues that cannot be resolved with one-on-one counseling, or just do not learn that way, or refuse to learn that way. B) We have the folks who need it and should not participate in it. These are the fanatics who abuse the mechanics of the religion to get what they want or as a crutch. C) We have the folks who don't need it, and are fed it. These are the folks who are brought up with religion and decide they do not need it and function normally and live a "good" life. D) Lastly, we have the folks who don't need it, and are not fed it. These are the folks who never participate in religious activities ever, and function normally and live a "good" life. There probably are more granular categories, but i'll just define the 4. Given that we have different groups of people, can we, how can we, or should we seek to eliminate religion? More importantly, if we should not eliminate religion then how can group C and D live free from persecution and live peacefully with groups A and B?
