My parents are this....and I love them, but neither I, nor my brother followed their "faith," for exactly the reasons you've laid out here. We were scorned long ago, and avoid their church. But, the Trump years laid a battery of new pain into that old wound.
I really don't have the words to express how broken my heart is...but yours come close to defining that pain.
I'm not religious, but if there is a 'god' it is love, and I can feel it in your words.
