Progressive Christians fundamentally disagree with your position that the Bible is the foundation of their religious experience. You don't seem to know much or anything about progressive Christianity, which is something that you might find very interesting if you looked into it.

The idea that a sacred text controls or defines personal faith is an idea that is not universal in faith traditions. For example, Hindus, Buddhists (the religious sort, I mean, not the purely philosophical sort), Jains, Sikhs, etc, have never centered authoritative texts as the definition or expression of religious faith. That's pretty much a traditional Protestant Christian thing, an idea Martin Luther advanced, and which he named Sola Scriptura, meaning loosely, "only the Bible."

When you point at the Bible in order to condemn all Christians, you are (I'm sure inadvertently) advancing a textualist philosophy that that many people of faith reject anyway.

Like I said, they're not even likely to be able to hear you, because they don't think the way you're telling them they're supposed to think.
