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"
As somebody whose primary language is Dutch, the lack of an explicit plural "you" is one of the worst things.
If I'm talking to somebody, I can't nicely refer to a group they are part of, because "you" means they themself specifically, "y'all" makes me feel like engineer TF2, and "you people" sounds condescending.
