I have to agree with you all about people who call themselves zany etc. I think that is why i won't join the red hat ladies, because their 'eccentricities' seem to me (from the outside) to be somewhat staged.
I'm not mainstream where I live, because I'm an immigrant with a funny accent, a very left wing Labour party member unafraid to voice my opinions, completely indifferent to fashion, and utterly indifferent to two important Australian issues - cars and sport. I don't drive - that is worse than being illiterate here. Also, I have nerdish tastes in entertainment - Doctor Who (I have a photo here of me with the Tardis), Star Trek, Harry Potter, Scandinavian crime drama, Big Bang Theory, and most good British drama.
I love to meet people who are different in some way - I was brought up to welcome diversity and now I feel threatened by massed mainstream society. I was once persuaded into a charismatic church's Christmas Pageant put on by Assemblies of God. It was a lovely production - costumes, camels, choral music etc, but something bothered me all the time I was there. Couldn't put my finger on it till I realised everyone there was white establishment! Not a dark face anywhere! Not a poor person to be seen. Not a handicapped person, not a gay person - no-one who was not utterly mainstream. It was WASP central. Scary!
