Gnostic arrogance from knowledge, especially knowledge that most people do not have, and conspiracy theorists
In the early days of Christianity, there was a heretical group called the Gnostics, who believed that secret knowledge was the key to salvation. You see, they thought they had special knowledge about how the world really worked, and that everyone outside the group didn’t, and thus couldn’t be saved. They were similar to the cults of the Egyptian god Isis that were popular in the Roman Empire at the same time, which promised power through secret knowledge. If you see similarities to the Free Masons here, you’re not alone.
I’m concerned that the conspiracy theory community (here and elsewhere), rather than looking skeptically at the world and seeking objective truth, is getting a gnostic arrogance about themselves. Be aware of this hubris. Just because you have figured out that XYZ that the conventional wisdom says is not correct, it doesn’t make you a better person, it just gives you better outcomes in life. Your mission, if there is one that is (that’s another debate), should be always seek truth as objectively as possible, and share it with others. If they refuse to listen, because a life of lies is a more comfortable one, shake the dust from your feet and move on.
Oh, I'm reading what you're writing, but you're wrong on the history. Pagans did the killing. Gnosticism was in rapid decline and Gnostics were few in number long before Christianity was the official religion of the empire and such things occurred under the banner of the church. Gnostics were killed same as other orthodox Christians, and other heretics, such as Arians, in various Roman persecutions.
Their books, written well after the 1st century AD and the time of Christ, infused with various mysticism, never made it into the Bible. That did the rest of the work.
As for your last sentence, when did I ever say we should/are/can do nothing? I specifically said otherwise, that we should educate people to the best of our ability.
