Meghan McCain spoke out on the debate over the use of the word "vagina" in the Michigan House, telling MSNBC's Ed Schultz that the Republican response to the word shows that "we're regressing as a culture."

"I'm a proud pro-life woman," McCain said during on an appearance on MSNBC's "The Ed Show" on Tuesday. "But when you hear that the word 'vagina' isn't allowed to be said by a congresswoman while debating women's reproductive rights, you can't help but thinking we're regressing as a culture when it comes to women's issues."

The controversy began last week, when Michigan state Rep. Lisa Brown (D) was barred from speaking in the state House after Republicans disagreed with her saying the word "vagina" during a debate over major abortion legislation.

“I’m flattered that you’re all so concerned about my vagina,” Brown said during the debate. “But no means no.”

McCain said that while she is pro-life, she disagrees with "humiliating" procedures that Republicans in other states have proposed, such as Virginia's maligned transvaginal ultrasound proposal.

"There's a difference between humiliating a woman and belittling her -- I dont believe there's any woman out there that's pro-abortion," McCain said. "It's an incredibly personal and complicated decision for any woman."

McCain, whose father Sen. John McCain (R-Ariz.) lost his 2008 presidential bid to Barack Obama, stressed that Mitt Romney should steer clear of abortion and similar issues on the campaign trail.

"As long as Mitt Romney keeps concentrating on the economy, he doesn't need to talk about anything else," she said. "At the end of the day, that's the only thing Americans are going to be concentrating on."
