Because in trying to show you proof<br />
They forget what they believe<br />
Then then what they wanted <br />
To proove goes<br />
I've often wondered if it's because the idea that you might actually be right scares them....?
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.
maybe they are scared you might be right?
