Coles was unprovoked, and there was no retaliation from an Argentine player.
Frizzell's retaliation wasn't the same as Coles' incident but retaliation is being regarded to be more penalisable than the first offence.
the AB's players did the slapping, not the argentine players, and "argy bargy" shoving in general have never resulted in penalties in matches. unless it escalates into a brawl. So I don't really see why you are so vehemently defending the acts of the AB players. Other than your devout support for them. Just take it on the chin man.
