What’s Better on a Passport: 'Mother' and 'Father' or 'Parent 1' and 'Parent 2'?

As if another battleground was needed over the subject of gay parenting, now the fight has moved into the air. Well, not exactly the air, but the airport anyway.

Thanks to the work of gay-rights supporters, the face of your passport could soon be changing in a way that may strip a bit more of your gender identity.

The State Department has announced that the words “mother” and “father” on U.S. passport applications will now be replaced with the more gender-neutral terms “parent one” and “parent two.” The agency said the change is part of an improvement intended to give a more accurate description of “a child’s parents and in recognition of different types of families.”

While gay parents cheered the news, Christian conservative organizations were quick to pounce on the news and decry the changes.

"Only in the topsy-turvy world of left-wing political correctness could it be considered an 'improvement' for a birth-related document to provide less information about the circumstances of that birth," said Tony Perkins, president of the Family Research Council in a statement.

Perkins, a longtime foe of same-sex marriage, said the gender neutral terms were "designed to advance the causes of same-sex 'marriage' and homosexual parenting without statutory authority, and violates the spirit if not the letter of the Defense of Marriage Act (DOMA)."

He was referring to the 1996 federal law that legally defines marriage as the union of one man and one woman.

The new passport applications will be available online next month.

So, which do you prefer? Mom and dad or “parent one” and “parent two?”
