People used to defend to the death others’ right to say things (that they may even disagree with): National Socialist Party of America v. Village of Skokie

[…] The injunction was granted, prohibiting marchers at the proposed Skokie rally from wearing Nazi uniforms or displaying swastikas. On behalf of the NSPA, the American Civil Liberties Union (ACLU) challenged the injunction. The ACLU assigned civil rights attorneys David Goldberger and Burton Joseph to Collin's cases. The ACLU argued that the injunction violated the First Amendment rights of the marchers to express themselves. The ACLU challenge was unsuccessful at the lower court level.

The ACLU appealed on behalf of NSPA, but both the Illinois Appellate Court and the Illinois Supreme Court refused to expedite the case or to stay the injunction. The ACLU then appealed that refusal to the Supreme Court of the United States.

Here is the interesting bit:

• David Goldberger is “a Jew”. [Once a Bastion of Free Speech, the A.C.L.U. Faces an Identity Crisis — The New York Times]
