A conservative activist, who has been billed as a homeschooling expert by tea party groups, warned over the weekend that sex-ed courses were a plot to increase the number of Democratic voters by destroying marriages.

In an interview with radio host Jan Markell, Marjorie Holsten argued that the only way that schools could teach sexual education in the Common Core curriculum would be to waive obscenity laws in many states.

"People say to me, why would they teach such awful things to our children?" she remarked. "If you go deep down and you connect those dots, you see that when children are desensitized to sexual things, that affects their ability at a later date to bond with a spouse."

"And so if you have somebody who can’t bond, they’re not going to have a stable marriage. When you have unstable, broken households, how do they vote? Democrat. So this has a very evil underlying intent."

Although she did not explain to Markell how children were supposed to learn about sex without sex-ed, Holsten did reveal to The Daily Show's Jessica Williams in 2012 that she had used guinea pigs to homeschool her own kids about intercourse.

During an interview about Holsten's objections to allowing a high school student to take a porn star to his prom, Holsten told Williams that teenagers should not be watching sex on the Internet.

"They should learn it the way I did, by watching animals do it on the street," Williams joked.

"Actually, that was how I taught my children," Holsten admitted. "We started with a boy guinea pig..."

"What? You taught your kids sex-ed with guinea pigs?" Williams interrupted.

"Well, we had a boy and a girl guinea pig that clearly liked each other," Holsten said. "You really couldn't see anything because they're big, furry little fuzzball things. I mean, that's why there isn't guinea pig porn movies."
