Nothing is more inefficient than the secretary of state thinking about and conducting meetings about the font used in documents. It just doesn't matter in the sense that it "doesn't move the needle".
I expect the leaders of a government deciding on matters that have a real impact on people's live, not on stuff that from a practical point of view is totally irrelevant.
So, two options.
a) It's a smoke screen. Do something bombastic and provocative so that the opposition chews on that while something else more "important" passes undetected.
b) Nah, he's just stupid.
In general, yes, but for these leaders... the less sabotaging impact they have, the better.
It's not about anything practical, it's all about the message.
The global impression of the US is worth thinking about. The font is part of that.
> not on stuff that from a practical point of view is totally irrelevant.
The modern era we live in has far, far too much of this attitude. It's the same force eroding craftsmanship, attention to detail, and human dignity.
I find it quite reasonable for someone to care about the presentation of official government communications.
And just so we are clear, I also think Rubio is a horrible person.
