Why does everyone descriminate against people who use there imagination?

[piosenniel]

You are what you are, don't fool yourself or anyone else, or you will live a life full of regrets.

What are your parameters for 'you are what you are'? - Does that include your imagined self? Or are you saying the imagined self is outside your real self - an extraneous thing you might acquire that is not central to your self?
