The phenomenon where one person suggests one thing and therefore another person thinks the exact opposite...?

Question

What phenomenon is illustrated by this example?
Let's say person A is a huge U2 fan, and person B is neutral, but hears a new U2 cd before person A. Person B tells person A how terrible the cd is and says "there is no way you will like it; it is terrible because of this and that." Naturally, person A (being the huge U2 fan) will very possibly come out LOVING the cd because person B has belittled something person A loved, regardless of what person B has to say about it.

I hope that was clear, but basically I am describing the phenomenon where one person has something they love attacked and therefore sticks even closer to that thing when someone else tries to attack it. Another example could be a Christian who only believes in creationsim more and more when arguing with an evolutionist who presents so-called "facts." The mere fact that the evolutionist is questioning it only makes the creationist stick to his faith stronger.

Can someone please tell me what this is called?
