I think all U2 fans are elite or elitist.
U2's music targets the intellectual elitist crowd. U2's music is for the rich, or the working class at worst. U2's music is for the educated. U2's lyrics are vague, they talk in riddles. One has to analyze their songs to actually grasp the music. U2's songs aren't straightforward.
U2 writes about viewing the world from the eyes of an intellectual, and then uses analogy or figurative language to describe the events or relationships. Whereas a band that has a less elitist target market would just say it straightforward.
Also, U2 views events through the "new media" or through the news (I can't believe the news today) or through satellite television. Babyface, for example, talks about the using the remote control. These are luxuries in life not all the people in the ghettos and the slum can relate to.
That is why U2's music doesn't appeal too much to the blacks. There are few blacks in a U2 concert. The direct approact to lyrics that doesn't require analysis is done by the rappers and hip-hoppers. And they write from the point of view of the person actually in the mud, not from the point of view of someone in the ivory tower seeing the mud and giving his own philosophical discourse about it.
So my answer to the original question in this post is that if you are a U2 fan, you are automatically elite. U2's music is designed specifically to appeal to the elite anyway.
The overly elitist fans look down on people who like everyday user-friendly direct music like rap, hip-hop, bubblegum pop, or Avril or Bon Jovi. They only like their own high-brow music like Radiohead, Coldplay, Beck, REM, Dream Theater, etc. while they riducule those who like the simpler music like Hanson, Britney or Eminem.
The normal U2 fans are elite but they aren't elitist. They may be up on a pedestal compared to fans of other music because they are probably more analytical and better educated, but they don't look down at fans of a different musical market segment.
