RALEIGH -- Protesters marched Monday night against North Carolina's recently-passed Marriage Amendment, saying it violates the 14th Amendment of the U.S. Constitution.

Last week, voters across the state overwhelmingly approved a change to the state constitution defining marriage as being between one man and one woman, which bans the possibility of gay marriage or civil unions.

But opponents said despite the vote, the fight against the marriage amendment isn't over.

“Gay, straight, black, or white. You can't take away our rights,” chanted about three dozen people as they marched from Nash Square in downtown Raleigh to Martin Luther King Jr. Memorial Gardens.

“It's important to continue to make a stand to show this is not over, that we're going to continue fighting, and that though they brought the fight to us we're going to bring it right back to them and win,” said Thomas Passwater, an openly gay man from Greenville.

The marchers believe North Carolina's now-approved constitutional amendment is unconstitutional.

“It's definitely a violation of the 14th Amendment because we're all supposed to be treated equally under the law and getting married or being able to work or being able to attend a school, all of that is part of what you need to be a human being,” said Marcia Everett, an organizer with 14th Amendment Equality Marchers.

Although North Carolinians overwhelmingly approved the marriage amendment with 61 percent support, opponents said it's never to late to make changes.

“What I want to see happen is for Amendment One to be repealed,” said Amanda Holland, a gay rights activist.

“We really want to make sure that everyone is treated fairly,” Everett said.

The 14th Amendment Equality group plans to host a march on the fourteenth of every month in various locations; not just in the Triangle, but across the state and across the country as well.

They plan to walk through neighborhoods, hoping to engage residents in thoughtful discussion.
