How to tell if a religion is B.S.

[Mystic]

The answer to the OP is if it goes from relying on God and those he has chosen, to that of humans he has not chosen. Humans he has not chosen can help God and help the chosen, but should never become a central or necessary foundation - as in no individual is an authority aside from God and his chosen.

Any religion that gives authority to humans God has not chosen goes against the central need of religion in the first place, that is the need of guidance from God.

All religions today as presented are a paradox.

Any people centering around non-chosen people with no proof from God they are what they claim to be, goes against the whole thesis of all holy books including Torah, Psalms, Gospels, and Quran.

If it's whole justification for evil constitutes 

But .. but freewill.....

or 

The best possible world 

or 

Dur you not all knowing so their might be some mysterious reason for it

The free will argument fails because it places an inherent value on free will which can't be rationally justified. Having free will may be valuable to us, but even if it is, that does not make it valuable in and of itself. Theists don't seem to think past this point. There is a lot of "makes sense epistemology" in theology, that theologists come up with a superficially plausible explanation and go no farther, as actually demonstrating the truth of an explanation is not their goal. Their goal is simply to establish that something is possible or consistent with the facts, in order to deny the assertion that theological beliefs are not true. Thus it seeks to guard, rather than establish, and so all its conclusions are mere shadows of truth, things that "might" be true, but not necessarily things that are true. This is the failure of theology. It is an epistemology based on the goals of apologetics, not based on a search for truth.

Religion isn't bullshit at all. It's very real.

Just the reasoning behind some of their sales product pitches puts me off a bit.
