This is a good description of me. If I see something is missing, I provide it. Like if everybody is on one side, I will become the side that is absent and fill the role. Even if I totally don't believe in what I am arguing. There is something missing and I pick it up. Even when it often means being the bad guy. Somebody has to be the bad guy, and the bad guy is bad for a reason. He is a product of something.
And I am always changing. The person you were debating with no longer exists later. He was used and discarded for purpose.

“A foolish consistency is the hobgoblin of little minds, adored by little statesmen and philosophers and divines. With consistency a great soul has simply nothing to do. He may as well concern himself with his shadow on the wall. Speak what you think now in hard words, and to-morrow speak what to-morrow thinks in hard words again, though it contradict every thing you said to-day. — 'Ah, so you shall be sure to be misunderstood.' — Is it so bad, then, to be misunderstood? Pythagoras was misunderstood, and Socrates, and Jesus, and Luther, and Copernicus, and Galileo, and Newton, and every pure and wise spirit that ever took flesh. To be great is to be misunderstood.”- Emerson
