The Louisville Human Relations Commission's annual race and relations conference is Tuesday.The conference features workshops on fair housing, economic assistance and civil rights. Commission director Carolyn Miller-Cooper says the goal of the conference, as in previous years, is to help familiarize Louisvillians with discrimination law."Race, religion, color, age—when it comes to employment, sex, sexual orientation, gender identity, religion and disability. All those classes are covered by our ordinance here in Louisville," she says.About 350 people are expected to attend the conference. That's in line with previous years, but Miller-Cooper says interest in the issues covered has gone up since 2008."Over the past two years, there has been an increase in civil rights in general in this country," she says. "And I believe we've had more discussion on the topic nationwide."There will also be a discussion of pay discrimination in college athletics. The keynote speaker is fair pay activist Lilly Ledbetter. This is the 15th annual race and relations conference.
