The United States Supreme Court is scheduled to hear arguments Tuesday in a case that pits abortion-rights advocates against religious groups dedicated to steering women away from abortion — including, some say, by outright deception.

But that is not why the case is important.

To be sure, National Institute of Family and Life Advocates v. Becerra has all the hallmarks of a classic culture-war throwdown. The case centers on California’s attempt to force so-called crisis pregnancy centers, which exist primarily to dissuade women from having abortions, to display prominent advertisements detailing the availability of state-funded abortions.

As The Times’ Adam Liptak put it, succinctly: “The centers say the law violates their right to free speech by forcing them to convey messages at odds with their beliefs. The law’s defenders say the notices combat incomplete or misleading information provided by the clinics.”

In certain ways, the case has played out just as one might have expected: The Conference of Catholic Bishops has lined up on one side and Planned Parenthood on the other. Most people’s opinions on abortion rights and their opinions on the correct outcome in this case are probably pretty closely linked.
