The photo is of text, which reads:
With the rise of capitalism, a new middle class emerged who wanted their children to speak the dialect of the “upper” classes. This desire led to the publication of many specific grammars. In 1762 an influential grammar, A Short Introduction to English Grammar with Critical Notes, was written by Bishop Robert Lowth. Lowth, influenced by Latin grammar and by personal preference, prescribed a number of new rule for English. Before the publication of his grammar, practically everyone—upper-class, middle-class, and lower-class speakers of English—said I don’t have none, You was wrong about that, and Mathilda is fatter than me. Lowth, however, decided that “two negatives make a positive” and therefore one should say I don’t have any; that even when you is singular it should be followed by the plural were; and that I not me, he not him, they not them, and so forth should follow than in comparative constructions. Many of these prescriptive rules were based on Latin grammar, which had already given way to different rules in the languages that developed from Latin. Because Lowth was influential and because the rising new class wanted to speak “properly,” many of these new rules were legislated into English grammar, at least for the prestige dialect.

please read this excerpt from a linguistics textbook about a rich guy that decided to change the way english was spoken just because he liked it better, then continue to belligerently argue that it is “objectively incorrect” to refer to someone with singular they pronouns
"they isnt singular for a reason" no actually, nothing in language is ever for a reason ever, stop pretending this is in any way a valid or acceptable justification for enforcing gender binary language
also, aave. those excerpts of what english was like before lowth decided he was important enough to govern how a language “should” be spoken are very similar to aave today. those of us that dont speak aave are the ones that changed!
