BOSTON, Mass. (WWLP) – Opponents of the “Bathroom Bill” told lawmakers on Tuesday why they don’t want to expand transgender rights. About a hundred parents and children filled the Grand Staircase of the State House Tuesday holding signs that read “No Bathroom Bill.”

They’re urging House lawmakers to vote against a proposal to prohibit discrimination against transgender people in public places, including restrooms. Under the bill, transgender individuals would be able to use the restroom of their choice.

Bill supporters believe transgender people should have equal rights, regardless of their gender identity. The Massachusetts Family Institute argues that such a law would put women and children at risk of sexual assault by male predators. “Any man for example, can walk into a women’s restroom or locker room and simply identify as female verbally,” the Institue’s president Andrew Beckwith said, “and then get undressed in front of young girls, stand there and ogle women.”

The state Senate passed a similar bill by a 33 to 4 vote. House lawmakers are expected to take up the issue in June.
