Not to be too much of a downer on this subject, but I think it's ridiculous for the official to ask a fan to be removed -- unless he was cussing, etc. Just "being a fan" is not enough to be removed.
How often do we see fans sent out of the stadium in high school football or basketball games. True there are more distractions and noise - band, crowd, etc. - but soccer officials are often quick to use their power to have folks banished from the stadium. It's sad that they have such thin skin.
