The massacre at the Charleston AME church last month reinvigorated the ongoing conversation about the confederate flag and its racially embattled history. Though politicians, activists and businesses have pushed for the removal of the flag from public places and stores, the opposition has been intense -- in fact, The Huffington Post reports that since the tragedy in Charleston, there have been 132 Pro-Confederate Flag Rallies throughout the country.

To add to this fervor, on Thursday morning (July 30), several confederate flags were found at the Ebenezer Baptist Church and the Martin Luther King, Jr. center in Atlanta. Mashable reports that the matter is now under federal investigation, and that officials are looking for two white men who were recorded on surveillance camera leaving the flags at the sites.

Martin Luther King, Jr. was baptized in the Ebenezer Baptist Church and eventually became a pastor there -- a position he held until his death in 1968.

Reverend Raphael Warnock, a senior pastor at the Ebenezer Baptist Church, called the act a "terroristic threat." "I view it as an effort to intimidate us in some way, and we will not be intimidated," he said at a press conference.

"This act by a cowardly and misguided individual or individuals is provocative to say the least. It ought to get the attention not only of black people but of freedom-loving people," Rev. Warnock said. "To place Confederate flags on the campus of Ebenezer Baptist Church after this horrific act in Charleston, in the wake of all this happening in our country, whatever the message was, it was clearly not about heritage, it was about hate."
