Those are called oxymorons. Jumbo shrimp, silent scream, deafening silence, sweet sorrow, forward retreat, pianoforte, and civil war (though civil war is technically not an oxymoron)

Everyone loves a good oxymoron. How about "honest Politician"

Abortion Doctor ... Abortion Surgeon ...

Religious War ... Death Row Sermon ... Political Integrity ... :)

1) "Contradictio in terminis (Latin for contradiction in terms) refers to a combination of words whose meanings are in conflict with one another. Examples are "liquid ice" or "square circle". If the contradiction is intentional (rhetorical or poetic), then one can speak of an oxymoron." Source and further information: http://en.wikipedia.org/wiki/Contradictio_in_terminis 2) "An oxymoron (plural oxymora (greek plural) or, more often, oxymorons) is a figure of speech that combines two normally contradictory terms. They appear in a range of contexts, from inadvertent errors such as extremely average, to deliberate puns like same different, to literary oxymorons that have been carefully crafted to reveal a paradox. The most common form of oxymoron involves an adjective-noun combination. For example, the following line from Tennyson's Idylls of the King contains two oxymorons: "And faith unfaithful kept him falsely true." Less often seen is noun-verb combinations such as the line "The silence whistles" from Nathan Alterman's Summer Night."
