Thank you for all your replies. Reading them all one by one and will act accordingly.
Can anybody experienced give me examples of their opinion of offinabus vs dissent that they had in real games? Does the home team manager saying to your face “you’re a F***ing idiot” when you don’t give a decision constitute a red…or is that yellow for dissent?
I'm actually having a semi-debate about that in another post. I was called a clown, on its own, not really a red card. But he ticked a lot of other boxes for me, that made it more than just the words, his actions. So I sent him off (he had walked a lot of distance to shout it in my face).
It is a combination of things. A manager calling me a F***ing idiot, crosses too many lines for me and is a red card. There could be mitigating factors like, you only just heard him and he was talking to his assistant etc. But for me it is direct, it is unfair. I would just have him removed.
If more of us do it consistently. It will happen less. I was 4th official recently, and the referee in the middle apparently had a reputation for having a very low dissent threshold. The manager was shouting at her and his assistant firmly said to him 'do not get her over here mate, she will book you'.
Everyone has their own tolerances and just play to your strengths. I'm usually fine, if players start saying things like 'there is two teams ref', I have a quick word with everyone on the next stop to cut it out and I let them know the consequences. "Calling the referee a cheat is a red card lads, so lets not do anything stupid today okay?". That is my approach and I am confident doing that.
Others will have a very different approach.
