Why do people ... ?

[Geoluhread]

Get pissed off when you have a fight with them, then you bring up a part of a conversation you had before with them shows them 100% guilty of doing (saying) something contradictory to what the fight is about (sometimes even you are having the fight for the second time and the conversation part was a solution for the first fight)?

They will consider it "using my words against me"
But you said it, take responsibility for it!!

And mind you, it's not bringing up that part of the conversation in the wrong place, like the press does. No, it's of the exact same situation!

URRGGHH!!

Some people have a problem of admitting that they're wrong.

Well Dale Carnegie said something along the line of 'you will never convince a person to change their opinion in public' which goes doubly when they are feeling strongly about something.
Also some people do change their minds in light of new information. Or find it easy to forget that they were convinced of something that they didn't really want to believe the first time round and then revert back to their original stance.
Dale Carnegie also said (something like) there are no winners in arguments about personal views, as proving someone wrong only makes them lose, and thus dislike you for it, which isn't usually a victory. Think about how many people you liked for proving something you wanted to believe or felt passionately about was wrong?
