Because in trying to show you proof
They forget what they believe
Then then what they wanted
To proove goes
I've often wondered if it's because the idea that you might actually be right scares them....?
Does it really matter?
If you're secure in your own beliefs .. isn't that enough?
They have issues lol and they start doubting themselves if they can't prove you to be wrong. Then it makes them mad if they know you might actually be right, even a little bit.
They're annoyed that you wont succumb to what they think is true to the beholder you look arrogant and foolish.
“Every man takes the limits of his own field of vision for the limits of the world.”

maybe they are scared you might be right?
