Professor Nara,
I don't understand as how belief system can fully influence the mere humans with all their senses?
Doesn't matter how relgious/spiritual a person is; doesn't matter how scientific a person is, discarding Religion/God/Spirituality; doesn't matter how rational a person is; doesn't matter how emotional a person is; doesn't matter how competent a person is in his/her profession; doesn't matter what the physical appearance of a person is; doesn't matter what his/her eating habits are etc..etc., can not substantiate any sort of claims that points out the immoral ways of a person, based on his/her belief systems.
Humans are humans irrespective of the life they been offered or acquired to live until death. Human's driving force to live and survive are - "NEEDS", "WANTS", "FULFILL", "SELF SATISFACTION", "ASPIRE", "SUCCEED", "ACHEIVE", ACHEIVE AS MUCH AS POSSIBLE", "SUSTAIN", "PASS ON TO KITH AND KIN", "SHARE WITH OTHERS AS POSSIBLE".
With long list of goals and targets, humans tend to act and react as per one's possibilities, capabilities and necessities. This process towards accomplishment makes humans deal with many internal and external forces. Either considering the "Low of the Land" or "The Theory of Karma", humans are surviving with the prime motive of self fulfillment, living along with fellow humans.
All the way towards accomplishment, humans tend to perceive/adopt different strategies to ensure as much success as possible towards attaining goals. No doubt, with the inbuild natural tendencies of selfishness (in the sense of self protection / acheivements / fulfillment etc), inbuild human psychology and rational brain. These inbuild factors are basically seldom influenced by one's belief systems that are in some way or the other for personal motives. Whatever the belief system may be, humans want a wholesome life with comfort, safety, security and the sense of fulfillment.
The crucial point here is, how humans are utilising or manupulating with all inbuild factors along with the feelings and emotions in order to acheive a desired wholesome life?
Humans with super brain and selfish genes are going to any extent when it comes to self, from the time immemorial. A religious and righteous person turns out to be cruel, crooked and disastreous and in reverse a non believer and or crude person turns out to be a humble, considerate, helpful, righteous and ethical. Humans seems to be changing colors during the passage of time, living their life.
Religion/God/Spirituality are aimed towards refining the qualities of mere humans. They were/are instumental in converting immoral people (theif, rapist, criminals etc) to lead a moral way of life. It helps humans to remain composed and righteous. These Religion/God/Spirituality are presented as a tool to attain refinement, righteousness, ethics etc..At the most, a sense of confidence, patience, hopes, considerations towards others and the tendencies to remain composed at any given circumstances.
Just because "mere humans" turns out to be immoral at any point of time in their life, can not subtantiate your claim that - "it (RELIGION) can surely force, and does force, a moral person act in immoral ways just to follow the prescribed religious rules. This is why religion must be rejected", IMHO.
Rejecting Religion/God/Spirituality based on "mere" human's negative tendencies, actions and reactions, can not be justified in support of rejections, IMO.
Religion/God/Spirituality is to attain inner purity to the best possible level and lead a righteous life with one's conscience and consciousness.
Off course Atheists have their right to reject the above statement. But accusing Religion/God/Spirituality for the crooked, wicked and immoral actions of humans (that can be found among Atheists too) can not be justified with assertion.
Humans are in plenty, humans are in different mask, humans are in different colors. It all just depends what they do to themselves and to others, positively or negatively. It just depends how and what efforts they make towards acquiring inner purity and be role models to others. Neither theism nor atheism can stand guarantee for the existence of righteous humans altogether on this Earth.
Theism provides individual opportunities to attain inner purity and self realizations.
