Amid recent widespread criticism and calls to take down the Confederate battle flag, a Louisiana man tried to get Wal-Mart to bake a cake with that image on it. When the store refused, he said, he got it to make one with the Islamic State symbol instead.

Chuck Netzhammer said he placed an order Thursday for an edible image cake printed with the Confederate flag and a caption: “Heritage not hate.” He said a store in Slidell, La., rejected his design. “The next day I had them do the same for the ISIS battle flag image I brought to them,” he wrote beneath a video he posted on YouTube. “They cheerfully did it and sold me my ISIS cake.”

Following the mass shooting June 17 at Emanuel AME Church in Charleston, S.C., many have called for the country to stop waving the Confederate flag. Companies including Amazon, eBay, Etsy, Sears and Wal-Mart have started pulling Confederate flag-theme items from the shelves.

“We never want to offend anyone with the products that we offer,” Wal-Mart spokesman Brian Nick said last week in a statement. “We have taken steps to remove all items promoting the confederate flag from our assortment — whether in our stores or on our web site.”

On Friday, Netzhammer posted a video, addressing Wal-Mart while sitting on a motorcycle and holding up the Confederate battle flag. The video has been viewed more than 500,000 times.

“Hi Wal-Mart, you’ve got some explaining to do,” he said. “I went to buy a printed cake from y’all the other day with this image on it and y’all wouldn’t do it. I’ve got proof. Went back yesterday and managed to get an ISIS battle flag printed. ISIS happens to be somebody we’re fighting against right now who are killing our men and boys overseas and are beheading Christians.”

Netzhammer filmed the original order form, which he said was rejected, as well as the receipt for the Islamic State cake — a total of $20.93.

“Wal-Mart,” he said “can you please explain why you are alienating Southern Americans with this trash that you allow to be sold in your store?”

“Our talented bakery associates take pride in what they create for our customers,” Wal-Mart spokesman John Forrest Ales said in a statement to The Washington Post. “It’s unfortunate that one customer sought to take advantage of an associate who did not know the flag or its meaning. This cake should not have been made and we apologize for the mistake.”

On Sunday, Netzhammer shared a meme on his Facebook page, showing what appears to be Islamic State militants standing outside a Wal-Mart. It reads: “Just here to pick up our cake.”
