Why do you hate Mensa?

If you don't want to join (or can't join) why not just leave them alone? Why does the mere existence of Mensa make /sci/ seethe so much? Please be specific and not generic "they're elitist" or "they're insecure". That describes lots of people. What specifically is it that Mensa does that impacts your life personally? Or they sending puzzle squads around to your homes to force you to play brain teasers?
