It’s a combination of words I use “Look !! it is what it is” I would give up the word “Look” and get rid of the !! when writing. I used this expression if and when I am challenged to accept or change the facts, fundamental principles or truth.
It’s not an expression I used for opinions including my own as I believe everyone is entitled to their OWN opinions BUT not their OWN FACTS NOR ALERNATIVE TRUTH. So if I am challenged I just shut it down with “look it is what it is ” written or verbally. I try to lose the “look”at times depending on how I am being challenged. What more can I say? It’s just what it.
