You oughta e-mail him and ask him! He's probably already written something on the subject that is every bit as outstanding as this short piece.
My hunch is that he probably wasn't talking about organizations, but individuals as he is usually much more concerned with individual rights, than so-called "group rights" that I don't think he thinks even exist!
I read the thread and enjoyed the other comments you made. I've fought these things so long and hard that I tend to get frustrated easily by comments like your initial one. Sorry 'bout that.
