I don’t disagree with anything you said. Indeed, I have had similar experiences myself, even though I am the prototypical professional white person that most churches are designed for in this country. But I am curious about one thing. I have a degree in philosophy and religion, which allowed me to to examine and compare all the world’s major religions. There is a lot that Islam and Christianity have in common in appealing to our higher natures, but there’s much to divide them. In particular, Islamic standards are far more rigid, and in many ways arbitrary, than those found in the Bible (at least the New Testament). Strict treatment and control of women, condemnation of those who fall away from the faith, and those viewed as blasphemous outsiders are but a couple of examples. There is a reason that there is a small, but particularly vicious, radicalized minority who follow Islam. I don’t think anyone who has grown up in the West would seriously consider embracing and living under the strictures of Sharia law.
Of the reasons you listed for leaving organized Christianity, many of them have to do with the arbitrary way in which the power structure protected itself and gaslighted those below them whom they viewed as a threat or disagreed with them. This strikes me as being equally true of many of the more influential mosques and political power structures in Islamic countries. Unlike western Christianity, penalties are far more serious than shunning, blaming, and disenfranchisement. A “transgressor’s” life may well be at risk. Think of the various fatwas that have been issued in recent decades against public figures.
You strike me as a dedicated, sincere seeker of a higher and more authentic faith. My question is, why do you think that Islam will be any different or better than Christianity? Am I missing something?
