Why is it that we are accepting a player disrespecting a match official this way. This is not about pride or ego. This is about a culture shift. As long as we accept (ignore) it, it will keep happening. We cant have it both ways. One the one hand we complain about authorities not take action when it happens, on the other hand when it happens to us, we don't take actions.
Because we have to choose which hills we die on. A quiet word of abuse can be difficult to accept, but it would also be difficult to accept a sending off for a reason that nobody but you and player know. Still, sometimes, quiet abuse can be necessarily sendings off. In another thread, I wrote about the need to balance the severity of the comment with the need for publicity. "You're stupid" requires significantly more publicity than, say, a racial slur. So, in essence, the severity of the comment will determine how public the comment needs to be to be addressed.
