And isn't 'black sheep' biblical - or is that 'lost'?
prophet is not without honour save in his own country since the question was about idioms. True, the underlying idea of being insulted and disregarded by the community depends on how well the audience are familiar with the historical background of this idiom. The same could be applied to Tdol's 'a voice in the wilderness'. Apparently, the crucial point about the two idioms is that they both imply the ideas expressed by this person are true, good and useful. In case they are not, Bob's 'lunatic fringe' might seem the closest, but doesn't it primarily mean that the person disregards/violates the norms of the society? Since the idiomatic language is the language of attitudes, could there be the same words/idioms for opposing notions?
As I said earlier to Linguist, "You seem to be assuming that English has a word for this. It may have - I can't think of one - but it may not."
Eleven posts later, nobody has come up with one yet. It seems to me that Tdol's 'voice in the wilderness' and Esgaleth's 'prophet without honour' come closest.
And re 'lunatic fringe', perhaps I don't need to point out that it doesn't occur just when the moon is full... :oops:
Another biblical one. (Not an idiom in English as far as I know.) Says Jeremiah:
Woe is me, my mother, that thou hast borne me a man of strife and a man of contention to the whole earth! I have neither lent on usury, nor men have lent to me on usury; yet every one of them doth curse me.
How about 'completely ignored tinfoil hats?'
If I'm getting the point correctly, I can suggest a few more:
Cynic, pessimist .... Gloomy Gus (lol) ... wet blanket, party-pooper .... naysayer... skeptic, scoffer, disparager .....
In an alternative light; outcast (n), pariah ... leper... Scrooge??
(Not a Teacher)
'Pariah' may be the closest word for this. It is an outsider who is held in disdain by a society or community. It doesn't give any indication as to the reason for it, though.
You could say something like:
"He is a scientific pariah."
That indicates his ideas are not accepted by the scientific community, perhaps even scoffed at.
