Support 51%19% Oppose

Wording notes: supplies the proponents' justification ('on the grounds of fairness and safety in single-sex spaces') inside the stem | does not mention transgender people or what the law would do to them

tilts_restrictive — the stem states only the sponsors' rationale and omits any countervailing effect, so respondents evaluate the bill's stated purpose rather than a contested policy
