An American pastor says children should be kidnapped from same-sex households, likening the freeing of children from gay parents to freeing slaves.

Bryan Fischer, spokesman for the Christian activist group the American Family Association, tweeted Tuesday, "We need an Underground Railroad to deliver innocent children."

With it, he linked to an article by a man who says growing up with two moms made him "confused."

"When your home life is so drastically different from everyone around you...you grow up weird," Robert Oscar Lopez wrote on the website of the right-wing Witherspoon Institute.

He blames his upbringing for making him a "social outcast" who has few friends, trouble fitting in at work and difficulty having a relationship with a woman.

In another tweet, Fischer linked to an article about a Mennonite minister who is on trial for helping a woman flee to Nicaragua with her daughter to get away from her former same-sex partner.

When @boopumpkins pointed out his suggestion "is called kidnapping and is illegal," Fischer replied, "So was the Underground Railroad."

He continued to defend his position throughout the day, despite many tweets deriding him.

A recent study suggested children of gay parents are much more likely to become pot smokers, unemployed, depressed, sexually victimized, sexually promiscuous and unhealthy. But many academics have criticized the study's methods, and one professor, Darren E. Sherkat of Southern Illinois University, said bluntly, "It's bulls---."
