I wouldn't call confirmed atheist and religious war oxymorons

If confirmation is taken in the religious sense, the former is indeed an oxymoron, and also a pun.

Religious war isn't necessarily an oxymoron - in fact, practically every religion subscribes to fighting the "good" fight in some form or another. OK, a fight that is more spiritual than physical may be meant, but waddya expect? Reason overruling gut reaction?

Here's a previous oxymoron thread, courtesy of wow:

It often strikes me that oxymorons and paradoxes should be meaningless, but quite often come across meaningful, and occasionally profound. You can almost think up a deliberate paradox/oxymoron and find meaning in it:

Blindingly obvious.

Infinitely well-defined.

Fantastically commonplace.

Brilliantly dull.

And - tightening the circle - there are enantiodromic words such as priceless, invaluable and bottomless (http://wordsmith.org/board/showthreaded.pl?Cat=&Board=words&Number=451)

Which all goes to prove that language reflects reality, in that opposites coexist all over the place, and at the extreme opposites have more rather than less in common with one another.
We don't live in a binary/boolean world.

Another contribution to the new Philosophy of Words forum, perhaps..
