"How Bathroom Fears Conquered Transgender Rights in Houston."

The headline in The Atlantic after Houston voted — 61 to 39 percent — against the Houston Equal Rights Ordinance, or Proposition 1, which would ban discrimination based on gender identity (and 14 other factors, including sexual orientation). The "startlingly simple" opposition message was "No men in women’s bathrooms."

"No one is exempt," intoned a narrator in one TV ad that featured a young girl in a restroom. "Even registered sex offenders could follow women or young girls into the bathroom. And if a business tried to stop them, they’d be fined. Protect women’s privacy. Prevent danger. Vote no on the Proposition 1 bathroom ordinance."...

Supporters pointed out that it was already against the law in Houston to enter a bathroom with the intent to harass someone....

That response doesn't address the problem faced by a business that would like to intervene but can't know the intent of the person following a woman. Also, people frequently want additional protection. I'm thinking specifically of gun control, which tends to be supported by the same people who would like to open up access to women's bathrooms. These people aren't satisfied by the argument that it's already against the law to commit murder and other gun violence.
