Think you need to get the blinkers off. Most cases it should be a yellow for that kind of challenge. It's definitely not a 'never a yellow' category. It's just completely unnecessary from him. I can accept debatable depending on your ref but you saying that shows you have no interest in a balanced view.
I don't care what he pointed to. Once you touch someone in the neck / face area - violent conduct comes into play. The VAR said it was a red and he gave it as a red. If you want to whine about it then you should maybe complain that he wasn't asked to go look at it on the TV.
The offside goal was that close it could've been given. Notice you don't make a comment on that because the decision went in your favour.
