Conservative groups urge school boycotts on holiday honoring gay rights pioneer.
A day celebrating the work of civil rights activist Harvey Milk has sparked controversy in California.
The group called Save California is urging parents to take kids out of school on May 22nd.
Milk, the first openly gay man to be elected to public office in California, was assassinated in 1978, just 11 months after winning a seat on the San Francisco board of supervisors.
Former governor Arnold Schwarzenegger designated May 22 "Harvey Milk Day" in 2009, shortly after Milk was posthumously awarded the Presidential Medal of Freedom.
