Opcn
Well concerning "loons"
et cetera...
There is no valid way to dismiss a "chtonic religion" when compared to other religions.
Worshiping dead hover-carpenters and certain "prophets" that encounter winged horses is just as "looney" as worshiping huge immortal cephalopoid creatures of unspeakable power.
All religions are based upon FICTIONAL ACOUNTS. All religious entities are merely products of imagination.
So the act of choosing a religion is merely the act of choosing which fiction you are going to glorify as some kind of "divine truth", and which imaginary creatures you are going to regard as real.
And Opcn, you know, if I absolutely had to pick some certain religion, I would choose some kind of Cthulhu worship over any other religion.
Just because Cthulhu has tentacles, and tentacles go a long way.
Even more, as a free bonus, "chtonic" worldview proposed by Cthulhu "cult" is obviously much less goofy than christianity, islam, most forms of buddhism and most "typical" gnostic traditions, it does not impose silly descriptions of universe that do not withstand critical scrutiny. Also, Cthulhu worship does not force you to follow a "moral" that lacks any basis, contains logical errors, and is unpractical and failing in every imaginable aspect.
My second best choice would be Islam (well, it offers a much goofier worldview, but, after all, it is prety agressive and straightforward, and thus more or less satisfactory), but
only if Muhammad grew tentacles instead of his beard, you know, Davy Jones style...
others say he just doesn't know that he was channeling the truth.
You know, that is a typical example of so-called "religious reasoning" (Okay, I know the term is an oxymoron). Top quality religious reasoning, worthy of the best christian apologetics (and christians developed one of the best apologetic traditions around)
