Christian conservative James Dobson warned recently that if the Supreme Court strikes down state bans on gay marriage, it could lead to a civil war.

Justices will hear oral arguments later this month in a case challenging bans in four states, with a decision expected in June.

Dobson, the founder of Focus on the Family, which he led until 2003, is the host of Family Talk with Dr. James Dobson, which is broadcast on over 300 radio stations nationwide.

In a recent conference call with fellow anti-gay activists, Janet Porter discussed her “restraining order” campaign, which calls on Congress to strip the Supreme Court of its authority to rule on the issue of marriage.

Dobson endorsed the campaign, then added, “I just think we need to be realistic about what we're up against here.”

“I mean talk about a Civil War, we could have another one over this,” he said.

“The country can be no stronger than its families. I really believe if what the Supreme Court is about to do is carried through with, and it looks like it will be, then we're going to see a general collapse in the next decade or two. I just am convinced of that. So, we need to do everything we can to try to hold it back and to preserve the institution of marriage,” he added.
