Mat Staver of Liberty Counsel appeared on Tuesday’s edition of “Crosstalk,” Voice of Christian Youth America’s flagship radio program, where he argued that homosexuality will destroy civilization as we know it.

When a caller cited Cleon Skousen’s 1956 book “The Naked Communist” to claim that homosexuality is part of a communist endeavor “to soften America for the final takeover,” Staver completely agreed: “Yes, Skousen has a lot of good writings. In fact, he mentioned that many years ago and here’s where we are today.”

“Same-sex marriage is the beginning of the end of western civilization,” he said. “It really is, it’s that serious.”

Staver said leaders in countries like Peru and Jamaica have told them that Obama is an “interventionist” “with regards to immoral issues,” warning that the president is “using our State Department dollars and the ambassadors that he’s appointed to promote abortion and same-sex marriage.”

He also decried America’s “shameful” opposition to Jamaica’s ban on homosexuality.

Staver recently traveled to the country to defend its laws making it a crime to be gay.
