Water usage is probably my biggest. Living in a high desert, my wife and MIL see no problem with filling one side of the sink with hot soapy water to wash a few dishes because “that’s just how I’ve always done it”, to watering the grass and plants for hours. All of this makes me mental.
You can identify as whatever. But I’m dying on the hill that third grade English taught me that they/them was third-party possessive often reserved for multiple people. It’s fine if you want to use it for your pronouns. But doesn’t mean I’m grammatically fine with it.
While many people do say that to simplify, the singular they has been in use for centuries. If you see a person’s silhouette in the distance and you want to talk about something that they did you will you they/them pronouns for them in most dialects of English.
