imageA former counselor fired from the Atlanta-based Centers for Disease Control & Prevention after refusing to advise a lesbian continued her legal fight on Thursday before the 11th U.S. Circuit Court of Appeals.

Marcia Walden (photo) asked the Atlanta-based judicial panel to allow her lawsuit against the CDC to continue. Walden claims she was wrongly fired over her devout Christian background after advising a lesbian seeking to discuss her same-sex relationship to seek out another counselor, according to the Associated Press.

Walden, who worked for a firm contracting at the CDC, was fired after the federal agency said her remaining on the job would alienate a portion of its staff, the AP said.

Walden’s case has been embraced by some anti-gay groups, including the Family Research Council, who are using it in their arguments against the Employment Non-Discrimination Act (video). On Wednesday, U.S. Rep. Barney Frank said he’s working on gaining additional co-sponsors before formally introducing the legislation, which would bar workplace discrimination based on sexual orientation.
