Is it really being contrarian, or supporting multiple views in intellectually stimulating discussions?

A few days ago there was a discussion on CORS where some people defended the thesis it made sites less secure, and others stepped in and defended that CORS in fact improved security. Both sides posted their rationales. Arguably neither position was right or wrong. It just depends on perspective.

A glass can be half full and half empty at the same time.

Is anyone being contrarian to point out either interpretation?
