Folks, most of what is being discussed are paradoxes. The major definition of a paradox is a
seeming contradiction, that is not actually a contradiction. (The other major definition of a paradox is a statement that seems true but actually
is a contradiction).
So to say, "such and such seem contradictory, but actually isn't" is to prove that it's a paradox.

In other words, "we achieve peace (or harmony) through the application of (ostensibly) violent techniques" is a paradoxical statement.
