Jim Carroll -
the lack of arguments here change my opinion one iota
AS far as I am concerned folk music is what it is documented to be

Julius Caesar -
I am constant as the Northern Star

The most common interpretation of Shakespeare's portayal of Caesar is that men who are incapable of listening to reason, who are incapable of modifying opinion in the face of facts are dangerous.
Of course, Will was talking about the Roman Empire's equivalent of Hitler (killed millions). Stalin (killed millions ) and Trump (working on it).
By 'dangerous' the bard was talking about the inability to bend in those who wield political power. The inability to bend amongst those who have done great work in collecting the folk traditions of - and advocating the human rights of - Irish travellers..... well, those sort of people are much more harmless.
