Tennessee State Senator Stacey Campfield on Thursday said it was “virtually impossible” for people to contract HIV/AIDS through heterosexual intercourse.

Campfield is the chief sponsor a bill dubbed “Don't Say Gay,” which would outlaw the discussion of sexual minorities in Tennessee's public schools before the ninth grade.

A last-minute amendment offered last year by Republican Senator Kerry Roberts helped the bill clear the Senate with a 20-10 vote.

The amendment strikes out language that limited the discussion of sexual orientation to heterosexuality before the ninth grade, replacing it with language that limits the discussion to “natural human reproduction science.”

The bill is now being debated in the House.

Appearing on Sirius XM's The Michelangelo Signorile Show, Campfield said his bill would allow children to concentrate on education and leave topics such as sex to parents.

“I don't think that's the teacher's job,” he said. “I think that's the family's job to do that.”

When Signorile asked, “What's harmful about [homosexuality]?” Campfield asserted that “AIDS came from the homosexual community.”

“It was one guy screwing a monkey, if I recall correctly, and then having sex with men. … It was an airline pilot, if I recall.”

“My understanding is that it is virtually – not completely, but virtually – impossible to contract AIDS through heterosexual sex. … [It is] very rarely [transmitted vaginally],” Campfield insisted as Signorile denied the claim.
