That poll gives no context about what various Christians actually think hell is.
You seem to be projecting your experience with Protestant fundamentalists, with all of Christianity world wide.
Bible thumping Protestants adapted Dante's 13th century caricature of hell as a literal place filled with instruments of torture.
My understanding is the Eastern Orthodox tradition does not hold that hell is a literal concrete place where the righteous are strapped to instruments of torture for eternity. That caricature sounds great in the epic poetry of Dante, but it does not necessarily represent sound theology. I believe the Orthodox tradition considers hell a state of being, rather than a literal torture chamber. A state of being representing separation from communion with God. Not all Christian traditions practice biblical literalism.
My take is that you are projecting your experience with bible thumping, fire and brimstone protestant fundamentalism onto the world's other Christian denominations
The fact that your parents dragged you to a Protestant fundamentalist church, and frightened you with visions of eternal tortures in hell is not the fault of other Christians.How many times are you going to repeat that “you’re emotional” bullshit before you actually read what I said? Most Christians believe in a literal hell. That’s fact. Prove it wrong if you don’t like my poll.
Protestant fundamentalists have hijacked Dante's poetic and fictional depictions of a terrifying hellscape.
The beliefs of your fundamentalist Protestants are not shared by the theologies of the Catholic and Eastern Orthodox churches. They generally interpret hell as a self-imposed separation of communion from God. The torture chambers and hellscape of Dante and your Church are your interpretations, not theirs. On this planet, I am pretty sure Catholics and Orthodox Christians outnumber the American Protestant fundamentalists you affiliated with.
"The images of hell that Sacred Scripture presents to us must be correctly interpreted. They show the complete frustration and emptiness of life without God. Rather than a place, hell indicates the state of those who freely and definitively separate themselves from God, the source of all life and joy. This is how the Catechism of the Catholic Church summarizes the truths of faith on this subject: “To die in mortal sin without repenting and accepting God’s merciful love means remaining separated from him for ever by our own free choice.
This state of definitive self-exclusion from communion with God and the blessed is called ‘hell’”
-- Pope John Paul II, 1999
