Well poseidon was respected-feared in the Greek world as the big 3 was the big deal of the millenia there, but in Camp Jupiter, or the "roman" world, he was far more feared, not as important as the most important are Ares and Jupiter, not alot of big three stuff. So posiedon's not respected as much, and might have been looked as a minor god.
