Just because someone is more successful than you at something doesn't mean that they are more capable of understanding anything else. When was the last time the world's greatest welder, for example, decided to hit us all up with their political feelings?
Idolization is not all bad though. Idolize someone for something they are actually good at, and then leave it at that.
Idolatry is hidden envy (a person may pretend that he loves his idol - but this is a lie)
