I intentionally left out YIMBY moral grandstanding, because it's usually a shield to hide the real reason they feel zoning should be changed: "I can't afford your neighborhood and I want to live there"
But usually it's something about how mixed use neighborhoods are better, or how someone on minimum wage can't afford to live on their own in a very expensive neighborhood. Ok, but those probably aren't the real reasons you're advocating for change. Just be direct.
Language that straightforward is surprisingly hard to find among the YIMBY croud.
