The decision itself is one that can go either way- I've seen good arguments for and against but ultimately only one person knows whether the act was clumsy or malicious.
The VAR conversation there is like three drunks all blurting their opinions across the pub table trying to drown each other out- there's no discussion as to what the ref saw, what he missed, what he thinks may have happened, clarification on specific questions. I get that it's a quick-fire conversation but is it even worth having? I'd sooner the ref be able to request a slow-motion replay for such a big decision.
As for "He's holding between his legs, I'm going red." I mean I'd be fuming if one of our players got sent off on that rationale.
