I've read that addressing a former....

...President as "Mister President" or "President X" is disrespectful to the current office holder. Perhaps someone could ask President Obama how he feels about that...

1. Sounds like a Faux News "rule"...

I prefer to add the "President" nomen when speaking of Pres Obama. I leave it off when talking about Trump.

I suppose that is disrespectful to Trump, but that's kind of the intent.

2. As I understand it, the person gets to keep the title - they retain it for life.

5. I think I would trust the opinion of President Obama

But maybe this Hickey dude is a Republican:

4. A couple of thoughts

1). I believe that there is some protocol of which I once read that a former President is technically to be referred to by the highest previous office that they once held. Hence it would be Senator for Obama and Governor for Clinton or George W. Bush. But I don't now the precise details of that, nor is it important.

2). How was George Bush referred to during the Obama Administration by the ones whom are calling for this?

3). Trump is so entirely disrespectful of pretty much everyone and every group, why do I care about how he is referred to or his predecessors?

4). If you want a friend in Washington, Get a Dog.

6. I was deliberately accepting the "rule" in my OP

OTOH maybe this highlights the need for :subtlety: smiley.
