Ryan Anderson, senior fellow at Heritage Foundation and founder of “Public Discourse,” joined Eric Metaxas on his show Tuesday to discuss the Supreme Court’s marriage equality ruling.

Anderson provided listeners with a historical backdrop to the ruling, arguing that for “the past 50 years heterosexuals have failed to live out the truth about marriage.” Heterosexuals mistakenly “bought into a bad ideology; it was called the ‘sexual revolution.’” This, he said, made “a mess of the family, whether it was the hook-up culture, pre-marital sex, non-marital childbearing, lots of divorce.”

“And once you have made a mess of marriage in those ways,” Anderson continued, “there’s a certain logic to redefining it to include same-sex couples: if it’s just about consenting adult romance, why not?”

“That whole 50 years has been a problem,” he said. “Same-sex marriage didn’t cause the problem, but same sex marriage will make the problem worse and it will make it harder to create a strong marriage culture.”

Anderson made similar comments earlier this year in response to an interviewer who lamented that “the widespread acceptance of contraception” was “the first domino to fall” on the way to marriage equality.”
