`I hope this makes sense to someone, but I'm trying to be constructive here.  Nationality is not merely defined by genetics as the current opening line implies.  And Racism is not simply defined as 'Genetic' differences nor is it simple to define .   As individuals we are all genetically unique but that doesn't mean we are all of a different race. And no matter how genetically different, we are all still human and thus part of the human race to which racists would sub-categorize.  The fact is that there are many forms and many definitions and so I say we cover them all.  My suggestion still stands to change the opening line. ``Racism is the belief that the human race may be segregated or sub-categorized based on any determining factor.``  ``A Racist is a person who puts the belief of racism into practice through action.``  Then we can list references and then list sub-categories with additional references throughout history.  And additional sub-categories could include 'Genetic factors', 'Nationality', 'Cultural', 'Religious', etc.  And I know this is a touchy subject, but laws do not define the meaning of words. It is the definition of the words that define the interpretation of the law.  `
