Name one that is and we can go from there. Keep in mind, you need to support your position with facts or you are just perpetuating delusional thinking.
Ahem. As I stated previously,
ALL religions are dishonest. That, by definition, names them all. Your turn.
Ok. No religion is dishonest. Your turn.
A great many religions are dishonest. A great many make spectacular claims to miracles which never occurred; claims to rewards (carnal rewards and a version of everlasting life) in some asserted supernatural realm in exchange for unthinking allegiance and a financial commitment to the belief system; claims to supernatural events in the future which are utterly contradictory to natural laws, etc.
So yes, most religions are dishonest to the core.
