An anonymous e-mail potentially sent to thousands of parents accused the Castro Valley High School in California of promoting a " gay agenda " in its diversity program last week.
The high school near San Francisco is the alma mater of lesbian MSNBC host Rachel Maddow.
The two-day Days of Diversity program, now in its ninth year at the school, teaches students about the history of their community and country, including inter-religious relations and civil rights, according to principal Pete Alvarez.
Whoever sent the e-mail thinks otherwise, however.
"I find out that the influence of the gay agenda at CVHS is much worse than I had been led to believe," said the message. "I already knew that most of my child's teachers were gay."
Officials are unclear how the sender obtained the e-mail addresses of parents, many of whom expressed disgust with the antigay sentiments.
