Getting away from Fox News and back to pronouns:
An “individual pronoun” is not a contradiction in terms. It is merely a singular, definite pronoun, as opposed to a plural or indefinite pronoun. By definition a pronoun takes the place of a noun in a sentence. But that does not mean that it turns into a noun. If you start out by naming a specific man and then referring to that man later in the sentence or paragraph by the individual pronoun “he” that does not mean that “he” has become a noun. It’s still a pronoun - just doing its routine job of standing in for the noun.
The Types of Singular Pronouns in English
Subject Pronouns - I, you, he, she, it
Object Pronouns - me, you, him, her, it
Possessive Pronouns - my, mine, your, yours, his, her, hers, its
Interrogative Pronouns - who, whom, whose, what, which
Indefinite Pronouns - another, each, everything, nobody, either, someone
Relative Pronouns - who, whom, whose, that, which
Reflexive and Intensive Pronouns - myself, yourself, himself, herself, itself
Demonstrative Pronouns - this, that
Also, the rise of the use of “Ms.” is something of an apples/oranges comparison to the notion of dreaming up and introducing a new pronoun. Ms. is merely a title - a respectful form of address. and as such is readily changed or altered. Pronouns, by contrast, are fundamental parts of speech - some of the basic building blocks of speech and grammar. Creating a new title is easy. It happens all the time. Creating a new pronoun is altering the fundamental elements of the structure and function of speech and happens very rarely, and never by simple decree of a committee, however well-intentioned that committee might be.
