I was asked by a student to answer a survey for his research/thesis. The last question really got me worked up.
10. Please write briefly how you feel about religion, atheism or your ideas related to faith.
Religion is rooted in authoritarianism -- that something, a higher power, controls us and humankind have no control over their lives. This is especially unfortunate to the uneducated/uninformed who surrender and sacrifice their lives to serve cults/ cult leaders believing that they will be redeemed by a savior in the end. Our elders on the other hand grew up not knowing any better and so they subscribe to it as parenting from the past generations is rooted in authoritarianism as well, where the parents are authority and kids cannot ask why. Religion gives some sort of reason and purpose to people who'd feel helpless and powerless in the middle of the universe where nothing is really predetermined. Simply, religion is placebo.
Development, progress and evolution made the world more rational and asking why and keeping curious and exploring is highly encouraged; and in my opinion, religion is an outdated concept.
If anything, religion is an arbitrary divide created (as race, gender, political affiliation, heirarchies, etc) and used to justify hate and wars. If people realize that we are all going through our lives with no definite purpose or reason, all suffering at the same time, maybe there will be more compassion, and more peace, because we grow to know that we're not competing. We will put spotlight on the human experience and we'll all be more likely to use our faculties of reason and logic because nothing really happens for a (vague, divinely predetermined) reason, and we'll understand more, learn, analyze and adapt more and from that greater progress will be the output.
