Out actor Jim Parsons is calling on Houston voters to uphold the Houston Equal Rights Ordinance (HERO).

HERO prohibits discrimination in housing, employment and public accommodations based on more than a dozen characteristics including race, religion, sexual orientation and gender identity.

Opponents of the law forced it onto Tuesday's ballot. Early voting ended Friday.

In an email to the Human Rights Campaign (HRC), the nation's largest LGBT rights advocate, Parsons endorsed Proposition 1, the ballot initiative that would keep the law in place.

“My roots in Houston run deep and I still have family and many friends who live there so, even though I can't vote in this upcoming election, the outcome of this particular issue will still have an effect on me and the ones that I love,” said Parsons, who was born and raised in Houston. “I'm asking you to spread the word to anyone you know in Houston: please vote YES on Proposition 1 in favor of the Houston Equal Rights Ordinance (HERO) to protect all of Houston’s residents from discrimination.”
