My personal opinion is that religion is arrogance and insecurity on the part of man. It is arrogance, because anyone who says they know what God
thinks, what God will decide, and tries to limit God by their rules, is at the very least placing themselves equal with God, and at worst, above God.
Religion is also insecurity in that it means those following it feel themselves too weak to be "good people" unless they are told by someone else
that they are.
So in answer to your question, I believe all religions are incorrect or pacifying at best, and dangerous at worst.
Still, religion does serve some good purposes. It provides most spiritual people a convenient and easy way to satisfy their spiritual needs, with very
effort on their part. Christians can be baptized, say they love Jesus, ask forgiveness for their sins, and they've pretty much got a free ticket. I
believe this is why it's one of the more popular religions. But the same can be said of any religion that requires a leader or a book to tell you how
to think or feel about The Powers That Be.
Even if one's particular path says you must labor for exactly 10,000 days, doing manual labor, eating nothing but millet, and pray twenty times a day
in exactly a certain position, and so forth... it is far easier for most people to do and think as they are told when it comes to religion, rather
than have any sort of deep introspection on a daily basis.
The One True Faith, in my humble opinion, is a personal lifelong journey in which there are no easy answers, no blanket names, and no leaders to tell
one what to think and do. It is a lifestyle, of waking up every single day, questioning one's own beliefs, morals, and ethics, to see if a chip in
the resolve, or a crack in the reasoning can be found. If one finds a flaw in what they believe, that flaw should be exploited and explored until one
it is a flaw, and how to rework their beliefs to account for the flaw. After enough time of doing this, one should be able to defend
their beliefs against nearly any onslaught of questioning, using rational and well-thought out answers. There are no secret hidden doubts, because
every doubt must be explored and considered, to find if it is a valid concern. But even more importantly, this process should make one secure enough
in their belief that they needn't care if others are convinced as well.
