"I don't know."

That's the answer the lawyer defending the California gay-marriage ban gave when a judge pressed him on how gay marriage threatened heterosexual marriage. This is going to be the biggest problem for proponents of banning gay marriage. There is no logical basis for it. Outlawing it rests on religious beliefs or the "ick" factor. There is no concrete proof that it harms children, raises divorce rates, or in any way has an adverse affect on society.

Gay marriage will be legalized. It's only a matter of when.
