Most religion are mixed with a lot of good, philosophical tactics to live life by; and then a whole bunch of BS is thrown in there with it to "help" make the BS more believable (the good ol' mixing a lie with the truth tactic... taught in many business mgmt classes). We've seen or heard of the dark side of just about every religion in the last few decades, so I would not fault anyone who stood as an atheist but to even applaud their decision to do so.
If you separate the BS ideas of religion (very EASILY spotted), and use certain tenants of it instead as a "philosophy" of what to do in certain situations in life, then that's about the only true benefit you can get out of it that's actually 'identifiable'.
