I disagree. There are many things in the Bible that are very clear. The idea that the Bible requires interpretation that can be variable is not true. The issue is that you need to read the entire Bible first. Unfortunately most people take bits and pieces out of context as proof for or against something, and they often never question it further because it supports their existing worldview.
And if they believe god is supporting them in their journey, which again can’t be refuted, there is not much you can say to stop them.
Except the Bible shows that God’s people should not be involved in politics. There’s no getting around that one.
