Gobsmacked means (among other things) utterly astonished or astounded. It is apparently British slang and I heard it for the first time about a year ago and was astounded that I had never heard it before that; after all I have lived a long life and it doesn’t take too much to astonish me any more.
Having said that, I was gobsmacked by the harsh criticism that our Prime Minister took, mostly from our government’s opposition, for saying something positive about Fidel Castro after his death last Friday.
Sure, he, Castro, didn’t live up to the standards of most parts of our world but as always, there are two sides to every coin, argument, and people.
We are striving for a world of peace, but we are not going to achieve that when the battering rams of criticism are directed at the peace lovers of the world for choosing to articulate the good points of people that others love to hate. That does not lead to peace.
The Prime Minister took to defending his remarks, which, in my opinion, he should never have had to do. Why should you have to defend being a decent and upright human being?
Even though I like the word, I didn’t like being gobsmacked in that way.
Fidel Castro once said, “I don’t know what day I will die but I am not worried about it. I enjoy celestial tranquility.”
If it is possible, as far as it depends on you, live at peace with everyone. Romans 12:18 NIV
My Precious Life 
It would never have occurred to me to put our Prime Ministers words in a scriptural context, but I certainly hope you are right, it would help to deflate my cynicism about politicians in general. I have to confess my first instinct was to think of it as a naive gesture overlooking a very checkered past.
Remember that saying, “if you can’t say something good, don’t say anything at all.” Prime example.
