Well I wouldn't agree with this view of Christianity completely,
imagine if a person is kind and generous, a perfect model of a
human being, but strongly opposes the idea of a god.
Many Christians would say this guy would go to hell.
thats their reality and views. they are entitled to their views
though, doesnt mean it is the truth or reality. perception is
reality to that person only.
yes its absurd and ridiculous on the hell thingy if a good and
kind guy who doesnt accept their teachings, will go to hell for
eternity. not only is this rude and nonsense, but cursing will
only go so far in a certain extent.
