SACRAMENTO, California (AP) — A family advocacy group is already challenging a new California law that adds lessons about gays to social studies classes.

Paulo Sibaja of the Sacramento-based Capitol Resource Institute said he started the process Friday for a statewide vote to overturn the bill signed by Gov. Jerry Brown a day earlier.

Advocates say the new law will teach students to be more accepting in light of the bullying that happens to gay students. It also ensures that students are taught about the contributions of people who are gay, lesbian, bisexual and transgender in social studies.

Conservatives opposed the law, saying it would teach children to accept homosexuality.
