I'm not saying allegiances don't change, I'm saying that they never fully die. They will always have a fondness for those clubs though. I know, because I know many people like that. Myself included, as a youngster I loved one team because of their players but now I support my home team of Brisbane. I still have a fondness of that team because of when I was a child and I remember all those happy memories.
You just want him to be the man that turned away from Real and walked towards the light. I understand, you're a passionate Cule that is in love with the club. But you are blinded by bias, Iniesta has no reason to hate Real Madrid, he doesn't need to, and from what I've seen he is a model professional that loves the sport. Of course he is going to look back fondly on his youth and remember all the players he idolised. It isn't black v white. I just can't see Iniesta mulling over how much he 'hates Real', I can picture that from someone like Fabregas or Valdes but not Iniesta.
