I used to have access to Mensa magazine. The stuff I read in it guaranteed that even were I 'smart enough' (I'm probably not) I would never, ever have anything to do with them. There were real shades of 'we are the master race' threaded through a lot of the members letters and some outright saying that the thickies were holding them back and should be ... dealt with.
I daresay they're not all like that, but the willingness to print that sort of opinion in their magazine troubled me.
