The ranter got what he earned. Until she fills some kind of Official or Quasi-official (may already be this) capacity she is a private citizen. However, what makes this worse, the ranter delivered the tirade in front of Ivanka's children, really bad form.
Personally, I am glad to see the Kushners flying coach, gives them some credibility when Ivanka starts talking woman's issues, family issues.
Daddy maybe a dishonorable idiot, but it does not mean his children should be abused by the public.
Life is like a PB&J sandwich
The older you get, the moldery and crustier you get.
Now, get off my grass!
