Mensa seems to have a 9-11 special interest group.

Because the only thing Mensans have in common is the IQ requirement, you can meet literally any type of person in the organization. Winston Churchill could have been a Mensan, and so could the Unabomber.
Mensa ping.
So how many of us Mensans are also freepers?
I too have been there done that. The thing that impacted me the most was that almost all Mensans are liberal.
I also noted that Mensa has around 50 percent membership among qualified individuals.
In my experience in two local Mensa groups, the Liberal members seems to be there to preen and show off their superior intellect.
Conservatives seldom stay in Mensa because Conservatives have usually got better things to do than exercise intellectual arrogance.
I am glad I joined and am now glad I am out of it.
