definition of discrimination is: prejudicial and/or distinguishing treatment of an individual based on their actual or perceived membership in a certain group or category.
When you analyse the screenshot above, you find a good example of a perceived membership in a certain group or category. You will find two categories that are mutually exclusive. Someone is either an "American people of Jordanian descent" or he is "Jordanian people". You cannot have it both ways.
There is a practical point to it as well. Because of this lack of common sense, a category like "Jordanian people" can not be used to populate Wikidata with people from Jordan.
My challenge to the Wikipedia community is: explain to me why I am wrong in considering this discrimination?
