That has nothing to do with science. Every atheist must, logically, see believers as delusional, and probably that is reciprocated. But all believers will also, necessarily, see as delusional any believer in the competition.
However, that does not entail that there are not coherent believers. It just entails that I would not expect them to be. So, I will never be disappointed, only surprised.
Hoping, of course, than in an attempt to be coherent they do not start to stone rebellious children, people working on Saturdays, or re-establish slavery. That would be suboptimal.
By the way, I am a girl.
