A new version of the Equality Act, a bill to include various sexual minorities in federal anti-discrimination law, was introduced in Congress earlier this month. It would extend to people who believe they are transgender the protections of the Civil Rights Act of 1964. But it is causing concern among the country’s Catholic bishops.

The Equality Act would take the law that ended Jim Crow into today’s thorny sex and gender politics. The law that forced opened the doors of Mississippi schools to black children would be applied to ensure access for transgender people to the bathroom of their choice.
