I was raised in a religious (Christian) household, and attended church 3 times a week through my childhood and teen years.

Initially I guess I started 'idling' on those beliefs and practices once I realized that the majority of churches were being run as businesses, with an eye toward making money for a select few as opposed to helping those truly in need. Throw in snake-oil televangelists and it further diminished my trust in those institutions and people. At that point I no longer went (or donated) to church, but preserved my own values and beliefs as a personal form of religion.

But then that all changed again.

Despite the strong possibility of being downvoted into oblivion by the rest of my answer, I am going to say it anyway, because it's the most honest response to OP's question I can summon. And maybe there's someone else reading this who has gone through the same thing.

The final blow to my faith and my upbringing was watching as my religious family and friends all self-inducted into the cult of [a prominent political figure]. To see them using their holy book and their pastors and their (false) prophets and their money to prop up and justify an adoration and worship of this figure's abhorrent and evil life became too much for me to accept. If you were to meet and talk with any of them today, they'd sooner tell you about the greatness of this particular person instead of the central figure of their professed faith.

And the ongoing weaponization of Christianity by this same political figure and all of his hangers-on has only served to further widen the gulf between where I am now and where I used to be.
