Disagreeing well

Throughout my life I have noticed one thing about people in churches. They do not disagree well. If you ask a question or have a different stance on something you are automatically labeled a "heretic" even if it is not heretical. Why is that? Could it be that the people in leadership think that they have the only correct answer? Do they think that they are the only ones that hear from God? I think not.

Shane Claiborne sees mean people.

"If there's anything I've learned from both conservatives and liberals, it's that you can have all the right political answers and still be mean. And nobody wants to listen to you if you're mean. One of the things we can do is learn to disagree well. I think there is a new conversation happening within evangelicalism in post-religious-right America that is much healthier. We can actually learn to disagree well."
