Residents will have their final say on the controversial nondiscrimination ordinance proposal which is scheduled to be voted on by the San Antonio City Council Thursday.

More than 700 people registered to speak in council chambers during Wednesday's Citizens To Be Heard session, and less than a third had spoken by 10 p.m. Wednesday.

Proposed changes include adding sexual orientation, gender identity and veteran status to the protected classes under the ordinance. 

Those who support the ordinance say it grants the LGBTQ community the rights they deserve. Those who oppose it argue it would discriminate against people who disagree with the lifestyle of the LGBTQ community by prohibiting them from expressing their beliefs.

San Antonio would join other major Texas cities with ordinances that prohibit discrimination based on sexual orientation or gender identity. The Human Rights Campaign says nearly 180 other U.S. cities also have similar protections.

San Antonio Mayor Julian Castro says the ordinance is level-headed and overdue. Castro was the keynote speaker at last year's Democratic National Convention and says the backlash doesn't reflect the city's values.
