Technically, it is not the population that “should” “be” represented, but the electorate’s interests. Not the people, not the voters, but the interests that they hold. The term “representation” is as poorly used as is the term “equality.” People are not equal; when people use the term “equal” they usually refer to impartial and equivalent moral value, used as basis to justify assigning equivalent rights and duties under law. As long as any individual does their best to work safeguarding and promoting the majority of the electorate’s interests, sex, race or any other variable is (or should be) irrelevant. The notion that “S/he is one of us” in no way guarantees correct performance of these duties.
