Even if someone is not religious we still believe silly things. The greater example is love. There are billions if people on earth yet we believe that the few we meet can produce a special someone that we will love more than anyone else. We see those people entirely different even if they are just like everyone else whom we haven't come close yet. It is as big of a belief and irrational thinking as religion.
Yes to some extend someone who is not religious can believe silly things, while not analyzing and question things. And probably the time living on this planet will not be enough to question everything and all. I tend to question everything although I will never succeed with everything, sometimes memory betrays you and in the beginning, someone gets well indoctrinated by silly parents, teachers and believers and thaught NOT to question. Indoctrination to believe! And it is wrong!
The main problems of believers are in my opinion:
- They can't accept that there a thing which is impossible to ever figure out in a lifetime, and they are afraid of uncertainty. So they prefer to believe instead of accepting not to know and never knowing at all.
- They are afraid of the dead and funnily I see the most hardcore believers ever grow in there believe in misfortune, sickness and jail. And if they ever overcome it the credit it to there beliefe and enforce their ignorance about there power to change things on there own. I am a god because I claim I am, and so it is for others, they can claim and act like gods or they can create their gods which make their fate.
Love is not a silly belief, so it is not an example. While falling in love is probably a chemical reaction, but must surely simple the desire to possess someone else for their own ego, love is sure a bond of trust and empathy. Three cases on my own, (okay I'm crazy), My parents, I'm in the retro perspective not sure if I ever loved them or if there is a certain level of love which could be applied. But let's see the love for my daughter, she causes me a lot of o trouble in my life (and also a lot of joy and questions, also questioning myself), but my feelings were so strong from the beginning and grew so exponentially, so I could say that I would probably do everything for here. And I know for sure that I do things for here I could never imagine I would do ever because I did it. With my wife it's different, the love to her grows because of the way through ups and downs together, because how she is, how she thinks, and the level I can talk with her. So she is not special to me because of a belief, she is special for me through experience. For both, I would kill the entire planet when necessary and for my daughter, I know for sure I would spare my life for hers.
In exchange, who tells me to love all persons on earth equal is very probably a liar and not even loving itself or want to deceive others.
Just my 2 cents on it.
