The mayor’s pronouns are she/her. But I agree with your point, and so do a very great number of San Francisco residents. The current/upcoming mayoral election is being predictably pushed as a big fight over law and order issues by big-money organizations (a lot of the money coming from silicon valley, outside of SF) and also by corporate-owned local media. The mayor is cynically playing to that tune in her uphill battle to get reelected. As if that weren’t bad enough she had to springboard this off of a cruel Supreme court decision at a time when her constituents are mostly disgusted with the court.
