Rolling Stone has a great post about Why Conservatives Increasingly Care Where You Pee. In short, this law (and the others like it in other states) have nothing to do with protecting people and everything to do with fear. The Republican party has gotten very good at scaring their constituents into action. Emphasis is mine:
It’s troubling that bathroom bills could be used in a naked ploy to dominate downticket races in this election, as it further demonstrates that American conservatives have perfected the art of striking fear into worried audiences. All it takes is the suggestion of danger to create a highly reactive response that could restrict trans rights even as the community makes its way into the daylight.
And that issue of safety of trans men preying on little girls in the bathroom. It hasn’t happened. But trans people are the targets of harassment.
Good job opening up an already misunderstood, harassed segment of society up to more harassment. Honestly now, how you even intend on enforcing this law? For the party of small government, it seems they’re awful curious about what’s in our pants.
