Victoria Nourse LAT oped hits the nail on the head about textualism:
Many think that the appointment of Judge Amy Coney Barrett to the Supreme Court will jeopardize the Affordable Care Act and abortion rights. But the reach of her antidemocratic judicial philosophy will go beyond those issues to put every federal law that conservatives oppose in danger.
Barrett, who has been on the federal bench for less than three years, is a conservative star because of her writings supporting the theory advocated by the late Justice Antonin Scalia known as “textualism.” This judicial philosophy is fundamentally at war with democracy. It would allow the court to rip apart laws that voters need and want.
