Another day, another campus fascist assault, this time aimed at squelching the speech of center-right Christina Hoff Sommers.

Sommers, an American Enterprise Institute scholar, argues that much of modern feminism betrays the movement’s founding ideals. The lefty kids think that’s violence.

She was invited to speak Monday about trigger warnings and safe spaces at Lewis & Clark Law School in Portland, Ore. But the space didn’t prove safe for her.

A coalition of progressive groups insisted that inviting this “known fascist” was itself an “act of aggression and violence.”

Their letter demanding the Federalist Society rescind its invitation made a now-common claim: “Free speech is certainly an important tenet to a free, healthy society, but that freedom stops when it has a negative and violent impact on other individuals” — equating reasoned disagreement with assault.

When the speech went ahead anyway, progressives interrupted it with loud music to drown her out, along with shouts of “No platform for fascists!’ and “Patriarchy, bigotry, hate: These are things we don’t debate.”

A school dean, Janet Steverson, then asked Sommers to cut her remarks short and start the Q&A. Bad enough that many students actively oppose the free exchange of ideas; now administrators are joining in.

It’s time for Congress to start withholding federal funds from colleges that don’t adopt clear rules to protect free speech — and punish those who disrupt it.
