Dichotomies Are Not Real

What is wrong with our society?  What is wrong with us? Why do we simplify every issue into two "sides?"  Here are a few examples from general debate and parlance:

1) Pro Choice vs Pro Life (Why can't you be someone who favors alternatives to abortion but someone who also believes in women making their own decisions?)

2) Increase taxes vs Cut programs (Why not both?)

3) Progressive vs Conservative (an artificial dichotomy if ever there were one)

4) Less filling vs tastes great (the ultimate commercial that describes this problem precisely)

It seems that every time we turn on the news we hear everything being debated from the extremes, when any thinking person knows that the fertile ground is in the middle.

We do this when we discuss writing and publishing as well and it's not helpful.  Here are a couple examples that will be familiar to anyone who follows writing/reading forums:

1) Traditionally publishing vs self-publishing (why not both?)

2) Genre vs "Leeterature" (give me a break)

3) "pantzing vs plotting" or "discovery vs outlining" (Why not imagine story by writing a loose outline, changing it as you actually write the story?)

4) eBooks vs treebooks (why must one replace the other?)

Why do we do this to ourselves?  Why do we allow our politicians to do this?  Why do we listen to news outlets that do this?  Is it that subtlety is beyond our abilities?  Is it that we're 'too busy' to really think about these issues and identify the truth in the middle?  I don't really know myself but it's sure annoying to me.  How about you?  Isn't it time for us to start talking in full color rather than black and white?
