University of Georgia students will rally Friday to show support for affinity groups after a social media user posted disturbing messages to a number of the groups’ Facebook and Twitter pages.

The user posted a racist message to the UGA Black Affairs Council Facebook page earlier this week, along with similarly offensive posts on Twitter and Facebook targeting the school’s LGBT Resource Center and Muslim students.

Caroline Bailey, UGA senior and president of the Black Affairs Council, took a screen-shot of the post on her phone and reported it to student affairs administrators, the Athens Banner-Herald reported.

The post read, “Why can’t you dumb dirty (racial slur) stop stinking up the place? Let UGA be RIGHT for good WHITE Christian students.”

UGA vice president for public affairs Tom Jackson told the Banner-Herald that he had seen the other posts targeting the other affinity groups, but he wouldn’t repeat them.

“Both are of a similar tone, using every bad word you can think of targeting a specific group,” he said.

Campus police were alerted to the posts Tuesday, the Banner-Herald said. They determined that the posts originated from accounts connected to a UGA student, but the student told police someone else must have created the accounts in his name.

UGA Police Chief Jimmy Williams told the Banner-Herald that police are contacting Facebook and Twitter to try to get the accounts shut down.

The march is scheduled from noon to 1 p.m. Friday on the Sanford Stadium bridge. Bailey told the Banner-Herald that the groups involved were hoping for participation from all people and groups across campus.
