“There are too many X” is usually a socially acceptable complaint.  With one key exception: If the X’s are people.  Declaring, “There are too many blacks” makes you a racist.  Announcing, “There are too many Jews” makes you an anti-Semite.  Lamenting, “There are too many gays” makes you a homophobe.

There are however some exceptions to the human exception.  The oddest and broadest: It is socially acceptable to say the words, “There are too many people.”  In most of American society, similarly, it is socially acceptable to say, “There are too many immigrants.”  It can also be OK for either men or women to say, “There are too many men here.”

Other exceptions to the human exception?
