Many people confuse the concept of rational and the idea of what is reasonable.
Love is not rational.
Art is not rational.
Beauty is not rational.
Humor is not rational.
Joy is not rational.
Yet, were most people to see a man who rejected love, humor, art, beauty, and joy we would conclude him to be unreasonable and imbalanced as a human being.
If someone makes a decision to live their life according to the standard of pure rationality, that would be their choice of course (that might be their choice, but human nature would bet on them failing to overcome all emotions).
If someone makes a decision to live their life according to the standards of pure emotion, that would be their choice as well.
To live life with a balance of intellect and emotion is considered wise and healthy by nearly all.
As a society we believe in love, humor, beauty, joy, art and God.
Those who have other beliefs form their own society and keep to themselves, shunning the ways of others.
Belief in God is very reasonable.
If a minority group concludes otherwise, fortunately for them if they choose to have alternative belief systems than the norm, and they live in a society society like America they are free to express their opinions. Americans believe in a live and let live way of life, as we were founded on the concept of freedom from persecution and ridicule of a chosen religion.
If some minority group think themselves superior to others, they are free to think so.
If they ridicule others for their belief systems, they are being irrational and narcissistic.
