Sometimes, in the past, I've continued an argument long past the point where I actually believed I could win it, at which point I just started contradicting everything that was said with more and more absurd arguments. I had actually become convinced that the other side was correct, but I was too adrenalized to back down, so my brain kept coming up with new ways to continue the argument. At that point, even I couldn't believe what I was saying, but I was too proud to admit it. I feel like some people are in that state constantly, with this inner need to argue against anything and everything, which in the end makes all arguments pointless.
