Dave Portnoy waves Israel flag in celebration after Holocaust denier Bryce Mitchell gets choked out at UFC 314

Portnoy, who is Jewish, was wearing a white kippah and waving an Israeli flag and Silva celebrated his victory atop the octagon cage. 

"Always fun to see a Hitler lover get his a-- whooped," Portnoy wrote on X along with the video of his celebration. 

Saturday night was the first night of Passover as well. 

Backlash surrounded Mitchell, 30, after what he said on the first episode of his "ArkanSanity" podcast in January, most notably his belief that Hitler "was a good guy."

"[Hitler] fought for his country, he wanted to purify [Germany] by kicking the greedy Jews out that were destroying his country and turning 'em all into gays," Mitchell said. "They were gay-ing up the kids, they were queer-ing up the women, they were queer-ing up the dudes."

Mitchell continued by denying the Holocaust ever happened. 

"There's no possible way they could've burned and cremated six million bodies, you're going to realize the Holocaust ain't real."

UFC CEO Dana White called Mitchell's comments "probably the worst" of the "dumb, ignorant s---" he has ever heard. 

Mitchell is now 17-4 in his UFC career, while Silva has now won 13 straight fights and owns a 16-2 record.
