Dozens of tech leaders on Wednesday issued a joint statement calling on states to add sexual orientation and gender identity as protected classes to their civil rights laws.

According to the Human Rights Campaign (HRC), the nation's largest LGBT rights advocate, lawmakers in 28 states have proposed more than 85 bills that target members of the LGBT community.

Backlash over an Indiana bill supporters say protects religious freedom but critics argue would open the door to discrimination against gay men and lesbians led Republican Governor Mike Pence to ask lawmakers to “fix” the bill.

“In more than twenty states, legislatures are considering legislation that could empower individuals or businesses to discriminate against LGBT people by denying them service if they felt it violated their religious beliefs,” the statement reads in part.

“To ensure no one faces discrimination and ensure everyone preserves their right to live out their faith, we call on all legislatures to add sexual orientation and gender identity as protected classes to their civil rights laws and to explicitly forbid discrimination or denial of services to anyone.”

More than 60 tech leaders signed on the statement, including Salesforce CEO Marc Benioff (pictured) and Microsoft CEO Satya Nadella.
