Do we need religion? will the world be better off without it?
Hell yes! As long as the religious nutjobs get raptured out of the world first. Wink wink.
If you want to solve a problem, any problem, you need to understand it properly. If you have the wrong "model" of how things work, it's highly unlikely you'll come up with the proper solution. If you have the wrong data, it's highly likely you'll draw the conclusion and not come up with the optimal solution. (Garbage in, garbage out.)
Religions create a non-fact-based model of the universe. One that says that God created things the exact way they should be and things can never change, or evolve. It's unlikely they can solve things correctly with that model of the universe.
It's not likely religion will ever go away completely, but it should be marginalized, especially in the US. It already has been in much of Europe. Although our constitution prevents the establishment of a state church, there are powerful and well-financed forces at work in our country to undermine that concept.
Religion is necessary for a time...just like labor unions. Both have served their purpose. Time to quietly bury them. Just saying.
It will take a lot more than that to make this world a better place. Try ridding us of consumerism, hate, greed, hunger for power, inequality, poverty and fear and religion will disappear along with these.
Absolutely, I spent a year working in Saudi Arabia and I saw the worst that religion has to offer!
Take it a Little Further... Will The World Be A Better Place Without Us? Can We Poll Nature?
Religion served a purpose for me when I was child. I learned that this world is full of people who are delusional and there are those who live and are grounded in reality. So I guess religion helped me to understand bullshit!
I have come across the notion of rhetorical truth. Which the state where even if something is not actually true it still has adaptive benefit. For example, the belief that a porcupine may shoot its quills. This is not true, but they'll stick you before you know it. So someone with the belief that they may shoot them operatively give them a wide berth and effectively benefit from a false belief. Now, not all the supernatural belief may be claimed to have adaptive benefits but there is likely a reason that the ideas persisted in society; because they fulfilled some role in society. For example, the beliefs in human history that prevented the spread of germs, while those beliefs had no idea what the true nature of the problem was nor understand it in the slightest, it had an adaptive benefit to humanity.
Religion often promotes more tribalism and may have rampant negative effects like exclusion, persecution, and fanaticism that holds humanity back from the pursuit of truth-seeking which should never end. However, some of its manifestation create well-being pursuance of strangers within the possibly wide group, which is of good progress recognizing a shared walk that we are here in, not just those of the same belief system but of all fellows on the planet. Anything that facilitates the desire for the well-being of strangers or creates broad connectivity is helpful. A common theme of almost all religions is that of compassion. So that a religion practicing such even for outgroup such as is evident in Christianity actually makes the world a better place to live even if the root driving factor is delusional. Also, a sense of responsibility for one's actions that almost all religions engender is of good moral fiber.
So, even though there have been atrocities due to religion and toxic belief that allow egregiously practices such as being burned at the stake for heresy, humanity would have simply had other reasons for their tragedies notwithstanding religious practice. Religion has played a crucial role in the progress that is morality even as it has added a good portion of senseless operative beliefs.
I don't think it would change much of the world, the problem is with extremists dominators who need to impose their view and power on others and this will always exist religion is just a justification, a tool to get where they want to go. Religions gone, there will still be other raisons for extremists dominators to impose their views like nationalities, economics, politics, philosophies, even sciences etc. There is no lack of ideology that they can use to impose on others.
My issue is that religious beliefs are extremely broad and each little thing (Luther the creator of the Lutheran/protestant church was anti-bullshit Catholics). Some people who believe in religion, some people who believe in monarchy and people who think they will be on the reasonable, right side of any argument. There is the thing that life should be fair. Conflict would not disappear without religion but just like having a bad snack in site in the house you might you're more likely to gain weight. People aren't the same and religion doesn't help. I think the world would be better without religion, but not perfect.
