For some people, everything is either black or white but no gray.  Unfortunately, most of life is gray.  Because of this, black and white people have a lot of trouble dealing with reality.

So, if you are not a black and white person but dating one, it will be a challenge.  And, if you are a black and white person and dating a black and white person, it could be a disaster if you don’t agree as neither of you will compromise.
