Planned Parenthood is constructing its newest clinic in Houston, a 78,000 square foot building that will be the organization's largest and what pro-life advocates call an abortion super center.

A Planned Parenthood spokeswoman told Fox News that a third of the space will be used to provide health services. The remaining two-thirds will be for administrative offices and classrooms for education and training.

But thousands of pro-life advocates from across the country demonstrated in Houston Monday, saying the site's location unfairly targets minorities because it is located in southeast Houston in a predominantly African American and Hispanic community.

"There's a better way to do it. Let's love. Let's show mercy. Let's help women in crisis situations but let's not go killing babies. It wounds women. Let's stop," said Lou Engle of The Call to Conscience.

"Abortion is the killing and shedding of innocent blood," said Alexandra Beery, a protester from Chicago.

Planned Parenthood responded to charges about its location in a written statement.

"Planned Parenthood chooses locations based on the greater community's need for our services and there is great demand in the Houston area. More than 1 million residents in Harris County lack health insurance and half are of reproductive age. Clients come to our health centers from all over Harris County, not just the neighborhoods near our facility.

"Women need to have a voice in what happens to their own bodies, which is why abortion remains legal right now," the statement reads.

Several dozen pro-choice advocates came to show their support for the new clinic during Monday's demonstration.

"This is a place where a woman can go and get an annual exam, get testing, get all kinds of things. And these people would like to see it shut down because they don't believe in access to health care for women," said abortion rights supporter Trish Scringer.

Planned Parenthood has operated in Houston for 75 years. It says one out of three women in the United States will have an abortion by the time they are 45 years old. Some of those women, like Shawna Kimbrough, say they regret their decision.

"I chose abortion at the age of 16. Today my son would be 19 years old, and so I came out here to be a voice," she said.
