BOSTON — Critics of Massachusetts proposals to extend non-discrimination protections to transgender people in restaurants, schools or any place that accommodates the public said the state should instead focus on the privacy rights of children and women.At a Statehouse hearing Tuesday, Andover Republican state Rep. James Lyons said the bills could allow a 14- or 15-year-old boy to decide he is female and walk into a girl's locker room."What about those parents who are concerned?" Lyons said.
