That seems simplistic to me. There are many truths within the doctrines of all the major religions.

Almost all literature contains nuggets of truth. Comic books contain truth. That doesn't make any of them holy or infallible.

I wouldn't call it a "truth", but most religions espouse some version of what we call "The Golden Rule":

The truth that all religions are bullshit.

There are positive messages in religious writings. "Let he who is without sin cast the first stone" "Judge not lest ye be judged" "do into other as you wish done unto you" Are these messages true? Some truth can be found in things you might not accept as a whole. Here's one. "A broken clock is right twice a day" not a religious message but fitting.

I would not say "all" religion, which I know is the point of omni. But religion is not ALL bad. Sure it is bullshit, but even shit fertilzes life in its own way. The teaching parts of religion that have any merit are really just philosophical points, and those may have some merit. They just get lost in the wash of ritual and magical thinking nonesense.
Some principals widely shared across religions include the idea of promoting charitable effort and helping others, of practicing empathy toward others, some concept of honesty, and to practice patience as well as encouraging responsibilty.

Of course most screw all up by teaching contradictory things and elevating FAITH--aka gullibility-- to a high virtue,

The very essence of truth is the belief in it. One person's truth is not true for another. So, religion as a whole cannot be truth for nothing as a whole can be believed. Even the most "devout" find elements that they cannot truly believe and need to justify that by calling it "test of faith". There are however, elements within each religion that the followers fully believe and therefore that becomes their truth.

Put simply - truth can be found in anything provided you believe it is so.

One can find more truth in a Zippy the Clown cartoon than in religion.

The truth is people are scared of the unknown so they make up an imaginary protector.

I would say anything telling you to be a good person, though how that is defined and if it is indeed carried out is the problem.

Ommmmmmm - Bullshit is everywhere. (George Carlin)

What is this penchant for creating words and then creating a pseudo reason for creating them.
Religions are merely devices for indoctrinating and thereby controlling the uninformed (ie. "ignorant" in its true sense) masses.

"What truths are found in any religion?"
All the other religions are bollocks

Every religion has SOME truth, which is how they sell you the rest. If a religious leader tells you a truth and follows it with something you are not sure about, you trust them because they told you a truth first.

They key is that no religion is true about everything. I'd first dismiss anytign supernatural or magical. Then I'd dismiss anything that claims if you believe it makes you superior or favored in the eyes of god or the gods. Then dismiss anything that denigrates others just for being who they are. If you are lucky about half of what is left will be truthful, depending on which religion you started with.

What good is a grain of truth if it is encased in a boulder of bullshit? You can't get to that small truth before you've been contaminated and choked on the crap.

None is the correct answer. Believers just keep on making it up.

Simple answer to your question in one, single word, NONE.

What truths are found in any religion?

I was going to guess spelling, but no.

In The Perennial Philosophy, Aldous Huxley wrote about ideas, concepts and beliefs that are common to nearly all religions. This is from the introduction:

“The metaphysic that recognises a divine Reality substantial to the world of things and lives and minds; the psychology that finds in the soul something similar to, or even identical with, divine Reality; the ethic that places man's final end in the knowledge of the immanent and transcendent Ground of all being — the thing is immemorial and universal. Rudiments of the Perennial Philosophy may be found among the traditionary lore of primitive peoples in every region of the world, and in its fully developed forms it has a place in every one of the higher religions.”

I would not describe all of those common concepts as “truths”, because instantly skeptics would demand evidence. The one idea that I would say is “true” is that our everyday world of the senses is only a symbolic and imaginary representation of “the ground of all being” or ultimate reality beyond.That concept has been thoroughly confirmed by science. Religions use different words, such as “God”, “heaven”, etc. but the meaning is the same

Perhaps they share aspirations rather than truth. Truth might be just whatever people agree it is or whatever works most of the time for the most people.

The truth about religion is they will take your money! Oh yes and they will not help the poor the sick the blind the lame or anyone (not wealthy.)
The rest of the truth is religion sucks..

If you are the member of any of these religious cults it is a truth that you will be the poorer for it. Religions are all about shearing the sheep, that's why they call it a flock.

A nice trend...but still built on a central idea that there's a mythical power out there.

Dr. Neil deGrasse Tyson explains it best...

the truth is that all religions are designed to control fear or humans (or both)

I think this is called 'Paltering' www.urbandictionary.com/define.php

It's insidious.

There some truths in all total system ideologies, whether religious or political. But those are interwoven with false assumptions, myths, inaccurate perceptions, and outright fabrications., Don't waste your time trying to sort the wheat from the chaff.
