California is one step closer to passing a bill that would allow achievements of the homosexual community to be included in its social studies textbooks.

The Fair, Accurate, Inclusive and Respectful (FAIR) Education Act passed the state Senate Thursday by a 23-14 vote.

The FAIR legislation would mandate that events like gay marriage and other civil rights facts involving the homosexual community be taught in California schools.

Supporters say the bill's purpose is to promote diversity and lessen the chances of bullying. But many feel the legislation undermines parental authority and supports a social agenda.

"Proposition 8 demonstrates that the majority of Californians believe that conjugal marriage should be the only kind of marriage permitted by law," Andresen Blom, executive director of American Principles in Action, said. 

"It is clear that proponents of same-sex marriage who could not win in the court of public opinion plan to use curriculum to impose their beliefs on those most easily influenced -- our children," Blom said.

The bill now heads before the California State Assembly.

If the FAIR Act passes, California would be the first state to include lesbian, gay, bisexual and transgender achievements in history books.
