sledging is becoming more and more now i wonder one day they will stop playing cricket and start sledging. So icc should take action to stop this sledging otherwise one day there will a match on sledging.
If someone wants to play the game as per their local rules and attitude, they should do that but only when they are playing local cricket.
Just like Americans who play "American Football" as per their rules and they are allowed to sledge or hit (push) someone. No other country plays "American Football"
But if you are playing any International sport, you have to follow International rules and not say that since we do it in everyday life cricket, we will do it in International cricket also.
I think Joe Root put it correctly, this is not Rugby
