There's a nastiness out there that wants to harm me with words. These are my enemies - the ideologues the populists the columnists who don't like the fact that I take them on toe-to-toe. What I try to do is tell the truth. It's not the coin of the realm in politics.
He's nice enough not to want to be associated with a nasty remark but not nice enough not to make it. Lacking the courage of one's nastiness does not make one nice.
Words can be said in bitterness and anger and often there seems to be an element of truth in the nastiness. And words don't go away they just echo around.
