In 1958, when Gallup first asked the question, just 4% said they approved of marriage between Black people and white people."My gut reaction is they are security risks," Biden said of people who were gay in the military and Civil Service, "but I'll admit, I haven't given this much thought."In the 1990s, like many other senators, Biden cast a series of votes that hurt the push for gay rights — from cutting off funding from public schools that were "encouraging or supporting homosexuality as a positive lifestyle alternative" to the Defense of Marriage Act in 1996.Now, as president, Biden rebuked the Florida law that constrains teachers talking about sexual orientation or gender identity, calling it "hateful" and vowed to "continue to fight for the protections and safety you deserve."Barack Obama nor I support redefining from a civil side what constitutes marriage.""
