I am looking for an expression to use in an argument to indicate a lack of regard for the qualifications of an opponent. (This would be used in the context of wishing to be judged solely on the merits of my argument, but this is not required in the expression I am searching for.)
I seem to recall something in a poem (or perhaps even a piece of prose drama) — something like “…care/fear not for prince or (?)…”. It would probably be 19th century or earlier. However googling for it is hopeless because of prince, and it may be gentleman or something else, anyway.
Ring a bell with anyone?
