An argument is a connected series of statements intended to establish a proposition. No it isn't. It's not just contradiction. Look, if I argue with you, I must take up a contrary position. Argument is an intellectual process.
Contradiction is just the automatic gainsaying of any statement the other person makes.
No it isn't. Sorry, the five minutes is up. Look, this is ridiculous. Oh, all right. That wasn't really five minutes, just now.
