Religion is only true to the extent that it explains aspects of reality, which then relies on painstaking theology and individual and communal striving. It's not even about filling in the gaps of science. Instead it's history, poetry, ethics, psychology, community, wisdom, motivation, etc, etc.
The big problem in Christianity is the theology is often *extremely* bad and very few people want to put any effort in, or when they do they risk getting crucified for saying anything contrary to the mob. Granted, Eastern Orthodox can be a lot better than other options. But even still, when the answer is that everything always comes back to the crucifixion or something like that then it's not going to work for a lot of issues.
The Bible has some extremely valuable works within in it, but most Christians never get through much of it, and so tend to only operate according to what they picked up socially or according to narrow instruction. Clearly this only goes so far in addressing the range of real issues in life. And when organized religion is working poorly in today's world then it's pretty rational to reject it along with the people attempting to spread it.
