We read:
"The Pro-Family Law Center has challenged Ninth Circuit Court of Appeals and United States District Court rulings finding the terms "marriage," "natural family," and "family values" to be hate-speech. The case involves the threat of termination of employment by the City of Oakland against two of its employees who used such words on an employee bulletin board. ....
In United States District Court, Case No. CV-03-03542-VRW, the California federal courts concluded that the terms "marriage," "natural family," and "family values" could be censored in a municipal workplace as hate-speech and in the interest of "administrative efficiency." (See here). Specifically, the City of Oakland banned the use of these terms on postings made to an open bulletin board provided to employees during the same-sex marriage debate in California during 2002 through 2003.
