I've never heard of the speech, until you mentioned it.
I was aware of William Jennings Bryant to some extent, however. IIRC, he was left of center, but an honest man who resigned from Wilson's cabinet over the lies surrouding the Lusitania and how America was sucked into WWI.
I read the speech and really don't see why it's so famous.
You don't know anything about William Jesnnings Bryant?
You've read the speech and don't understand WHY it's so famous, or why it's pertinent to this discourse?
Then there's no point in trying to debate or discuss anything with anyone as obtuse and ill educated as you are.
