Without reading this thread fully, I will make the following observations:
a. Racism has never EVER existed in India. Discrimination of other sorts may have been there, but no, not racism. WE have never barred people from society based on the color of their skin. (It was always based on caste and at times, religion.) I am not saying one form of discrimination is better than the other. They are all equally bad but the thing is racism is alien to India as casteism is to Australia. It is still very hard for me to imagine that the jerks who did shout out "Black monkey" or whatever meant it in a racist way. In India, we get guys of all colors too pretty much and it is not unusual to be called a "white monkey" or a "black monkey", but given the fact that racism just about does not exist in Indian society, it is never meant or taken with a racist point of view.
b. Having said that, it is high time for our crowds to show sensitivity to other nations' and cultures. It is obviously a bad thing to be said to an Australian and the police and the association staging the match should be reprimanded for letting it happen. The crowds need to be educated on what is ok and what is not ok when it comes to bantering at the players and the buck should stop with the security guys. It is obviously only the first such incident (and from archie's opening post, I guess it is not exactly corroborrated outside) but keeping that aside, strict measures should be taken henceforth to make sure nothing is said which affects players' sensitivities.
c. Symonds doesn't exactly strike me of the sort who will play nice. We should still find out if stuff was actually said at him. And he, along with other players, should also learn to conduct himself. If you keep sledging Indian players or getting in their faces, crowds will get abusive towards you. There is a reason why there should be a code of conduct for players and while the odd sledge and glare may be ok, constantly sledging and getting in the faces of players, esp. icons like Tendulkar will mean crowd trouble. What he does is basically a flame bait. I won't be surprised if we see some racist sledging by some idiots in the Aussie crowd at Sreesanth, if he continues down this stupid path as well. Again, some part of the blame should go to Sreesanth in that case. Not that it is ok to tell racist stuff, but players should also behave in a way that is seen as acceptable. And I think both Sree and Symonds have been way over the mark in this issue.
d. What the hell is up with whatever Symonds said? Is he basically saying the Indians that the Aussie crowds will racially sledge them because that is what happened to them over here? And what the hell is this hostile reception he is talking about? It is one thing to sledge a national cricket team and quite another to utter absolutely ridiculous **** about a nation itself........
