Lets try something different. Some history maybe.
Beating a dead horse is an
idiom which means a particular request or line of conversation is already foreclosed, mooted, or otherwise resolved, and any attempt to continue it is futile. In
British English, the phrase is usually rendered as
flogging a dead horse
The first recorded use of the expression with its modern meaning is by British politician and orator
John Bright, referring to the Reform Bill of 1867, which called for more democratic representation in
Parliament, and which Parliament was singularly apathetic about. Trying to rouse Parliament from its apathy on the issue, he said in a speech, would be like trying to
flog a dead horse to make it pull a load. The Oxford English Dictionary cites
the Globe, 1872, as the earliest verifiable use of
flogging a dead horse.
