Maybe this analogy will help: joining a high-IQ club is not like joining just any athletic club. It's like joining an athletic club that's restricted based on a metric. What if you wanted to join a hiking club in your area but found out the only way to join was to prove you hiked X mountains first? I could see why that would turn some people off. It's not the interests; it's the cutoff.

Huh? Plenty of clubs are like this, especially athletic clubs, but all sorts of clubs have cutoffs. E.g. improv clubs have auditions, chess clubs have ELO rankings, and so forth.

Sure. My point was only that Mensa is not _just_ a club about a shared interest, which was implied by the examples given by the person I responded to. I suspect it's the cutoff that people don't like.
