Where you see a "cute little foot shuffle," I see a ref stopping to point at the penalty spot. Where you see a ref "looking to influence the moment," I see a ref getting accosted after making a correct call.
I get that the foul call came at a crucial time. I give the ref credit for calling it, as it had the strong potential to influence the outcome. But it was unquestionably the correct call. And the ref got mobbed for making it, which can't happen either. I have no problem with the red card in that situation.
