Republicans would demand she prove that she was not “working with our enemies.” That’s what Glenn Beck, the conservative radio host and conspiracy theorist, called for when Keith Ellison was elected as the first Muslim to Congress.

They’d probably use her faith to accuse her of hoping to create a “Shariah state” through judicial activism. That what conservative bloggers did in 2011 when Gov. Chris Christie of New Jersey nominated Sohail Mohammed, a Muslim originally from India, for a seat on the Superior Court of Passaic County.

If Judge Barrett wore a hijab, Jeanine Pirro, the Fox News host, would question whether her religious beliefs were in opposition to the Constitution. That’s the ugly accusation Ms. Pirro levied against Representative Ilhan Omar of Minnesota in 2019…

Judge Barrett co-wrote a 1998 law review article about the moral and legal “bind” that death penalty cases might present Catholic judges. What if she had been Muslim and had written about Muslim judges instead? Would Ben Carson call her “schizophrenic?” In 2016, that’s how he described Muslims who embrace American values like democracy and the separation of church and state.
