Hmm, seems like you had a lot of information misfed to you as you grew up. But the good news is that the issue has been identified as far as where your black and white thinking comes from and that is half the battle. Unfortunately it take years to alter the thinking and push it towards a different point of view.

I'm sorry that black and white thinking was forced so thickly on you. Hopefully this is a thought process that you will be able to change.
