It's the other people in the church that are being gullable. I am slightly fearful of telling them it's fake.
That is reasonable. The problem I have is with your Pastor. You said:
The head Pastor of my church completely agrees with me, and immediatly stopped showing pictures of orbs, once I presented him the facts.
The problem is that he just stopped using that example. He did NOT speak out to the members and tell them the truth, and did not start a class and sermons on critical thinking and bullshit detection.
We need more and more of the Christian Clergy to speak out against the liars and conmen that seem so common in the US Evangelistic and Fundamentalist movements. He is supposed to lead the flock, to guide them. Simply stopping using one example isn't the answer. Our Clergy needs to be actively teaching folk how to detect such nonsense.
