Simple dissent should not be a Red card. If there is profanity, abusive language (I am going to beat you up), or insulting language, then it would raise to the level of a Red card ejection. Even profanity may not be a Red card. If a player shanks a shot and yells “f##k” out of frustration, I am not issuing a Red card but will tell them to watch their languag.
I agree with you. The question centered on Grace placing fighting/spitting/dissent categorized together. I have always expected the first 2 to be rec-card-worthy, but not the last.
