Anderson, Indiana City Council has unanimously approved an ordinance extending legal protections to the lesbian, gay, bisexual and transgender community.

Approved last week, the ordinance adds sexual orientation and gender identity to a list of classes protected from discrimination in the areas of housing, employment and public accommodations.

According to the Human Rights Campaign (HRC), the nation's largest LGBT rights advocate, almost 20 Indiana cities, including Indianapolis, Terre Haute, Columbus and South Bend, have approved similar ordinances.

Republican Governor Mike Pence's signing of a version of the Religious Freedom Restoration Act (RFRA) earlier this year led to several companies threatening to boycott the state, arguing that it would allow businesses to turn away gay and lesbian couples. It was seen as a Republican response to defeat of Indiana's ban on gay marriage and the unraveling of a proposed constitutional amendment aimed at strengthening its definition of marriage as a heterosexual union.

Pence at first defended the law, but later asked lawmakers to “fix” it with an amendment which states that it cannot be used to discriminate.

Two groups opposed to LGBT rights recently filed a legal challenge to Pence's “fix,” arguing that it violates their religious liberties and freedom of conscience. The lawsuit also challenges several city ordinances similar to the one approved by Anderson.
