No more delusional than believing in evolution, or the same thing that science used to believe that the Earth was flat. The same delusion believing that you have total knowledge in all things. No more delusional than people saying that there is no God can not be proven.
All religious people seem delusional to me. They all believe magical creature(s) exist, completely unsubstantiated and most of the time demonstrably false.
No way everyone has different opinions, i do not really see how you can believe in god because the bible is metophorical and not based on reality, so when does it come to a certain point when it is real? And if there is no point, which i dont see, then god and religion must be made up? Just saying, but i think christians find peace in believing they are here for a reason blah blah. And the church hates gays and stuff its all so wrong and just a way of controlling people, but i do believe in the morals the bible tells us and the lessons you can learn for your own wellbeing.
Well obviously their religious beliefs are delusional but some (most?) manage to mentally compartmentalise their beliefs so that they can for the most part function as rational human beings in other areas.
