ALT TEXT:
- Panel 1: A person with the text “Singular ‘they’” written on them smiling with open arms.
- Panel 2: “Singular ‘They’” beaten up by others who said, “Singular they is ungrammatical. It’s too confusing,” “How can anyone use plural pronouns for singular,” and “Every pronoun should only have one purpose.”
- Panel 3: “You” hiding from the mob who was beating “Singular ‘They’”
- Panel 4: “German ‘Sie’” hiding with even more fear next to “You”
Edit: rewrote everything because it’s actually easier than I was explaining it:
It’s not about being polite or rude, it’s an indicator of your relationship with the person/s you’re addressing.
It’s not like you can choose how you say something to set a certain tone. „Would you pass me the butter, please“ doesn’t get more polite using „Sie“.
Who you’re talking to defines what to use.
When you are introduced, it’s easy: „Hey Bob“ -> informal -> „Du“; „Hello Mrs. Robinson“ -> formal -> „Sie“.
It only gets complicated because it also is used when you do not know each other, like on the street, at a restaurant, etc.
Then it’s a judgment call what to use depending on the context. Either there’s some social clue (age, location, class, etc.), or whoever goes first sets the tone, but it’s still pretty much along the lines of „would I call her Kathryn or Cpt. Janeway“.
