There are certain speeches I just don't think people should try to imitate, this is one
JFK 's speech was about the meaning of freedom in the context of the Cold War.
Harry's speech is about the Invictus Games.
He did not try to imitate a speech about freedom and the Cold War.
He used one phrase, as a pun, as many others have done before him.
See Bill Clinton in Cologne in 1999 among many.
In fact, as JFK said himself, his punchy phrase was not original to him but was itself a pun on a famous statement from Cicero: Civis Romanus Sum, I am a Roman, or I am a citizen of Rome.
I get it, you don't like Harry. It's clear on every thread that you don't like him.
But it is silly to take umbrage at a pun on a famous phrase, which is itself a pun on another famous phrase, and that its audience delighted in.
And that's all I have to say about that!
