gavaskar doesn't know any better. you see this everywhere in indian male culture. they are violently insecure, a trait they share with the other inferior men like the australians, so any threat to them must be belittled or lashed out at. gavaskar was intimidated by the crowds but lacked the mana to confront them like a man should, so he wrote some words in a book years later when he was safely out of danger.
of course, if you force the indian male into a corner, he will lash out defensively as we see with harbhajan singh in an airport when staff asked him to clean his shoes. of course i have to be fair, harbhajan cannot be expected to show some spine when his skipper was terrified of grass and spent most press conferences ranting that grass is an unfair surface to play cricket on.
moving back to the australians, i think it's fairly obvious the reason they are so good at fast bowling is because some misguided souls feel the need to become alpha males to protect their beta male friends in the side they feel sorry for. the australian batsman understands his home conditions, but is confounded by the moving or spinning ball. his reaction to this is to chat it up because cricket is a non contact sport, but as the stopped clock gavaskar almost observed correctly, an alpha male might make it a contact sport.
so the alphas in australia learned to bowl fast and protect their friends, and the unfortunate side effect is this has only made them chattier. it would be kinder for the alpha quicks to let nature run its course.
i think it is fairly obvious that had brad haddin chosen to applaud jesse ryder from the field instead of martin guptill, brad haddin would have been celebrating the success of mitchell starc that evening in the intensive care unit on life support. if michael clarke had threatened to break roy gilchrists arm, he would be dead.
