That's the only description which can be applied to the comments thread attached to The Standard's gross and fabricated attack on John Key's remarks concerning the Oslo atrocity.
The original post sounds as though it was written by Trevor Mallard. It has his fingerprints all over it. The PM's statement is edited and mis-stated to completely change it's meaning and context.
But the comments which attach themselves to his carefully contrived but sinister aspersion tell you all you need to know about the left. And that is:-
These are the last people on earth you would ever again trust with the reins of government in new Zealand.
They are toxically insane.
