SAN DIEGO -- Some local parents are protesting an abstinence-only sex education talk presented to nearly 2,400 students at Coronado and Grossmont high schools Tuesday.

The parents are angry because state law prevents schools from discussing abstinence without also discussing contraception. In one excerpt from the discussion, speaker Pam Stenzel said, "No one has ever had sex outside of marriage who didn't pay -- no one."

"We have been contacted by a lot of parents ... angry over the district's flagrant violation of state law," said Vince Hall, spokesperson for Planned Parenthood. "Abstinence-only sex education is not consistent with state law because it tells kids that contraception won't keep them safe and that any sexual activity before marriage will result in disease."

Grossmont High School District's Catherine Martin said the lecture falls outside the law's boundaries because it was intended to be motivational, not educational.

"It's common for ASB to bring in motivational speakers and that's how they billed the Pam Stenzil's speech," Martin said.

Critics say parents were not given enough notification to allow their children to opt out of the presentation.

"The flyer they gave them never mentioned it was an abstinence-only advocate," Hall said.
