This is the point Jesus was making. From the NIV:
"...anyone who says, You fool! will be in danger of the fire of hell."
In danger of Hell's fire, just the same as if you killed someone. Got it?
I knew you did.

That's what the book says.
Oh?
Since when?
Jesus seemed to 'insult' the Pharisees quite regularly.
Does HE get a pass that I don't?
