Is India right in talking against racial discrimination

There has been a lot of media hype about the racial attacks on Indians mainly in Australia. Media blew up the issue saying Australian are racially motivated. But we as Indian, are we right in even complaining against the discrimination when there is so much of discrimination among ourselves interns of castes and religion.
It is a known fact that Indian has a long tradition of caste discrimination. The discrimination is to such an extent that so called dalit are not even allowed to step into the colonies of the so called upper castes. The very problem of naxalism is dogging India just because of this discrimination. When we have such a big problem on our lap, is it right to talk about the discrimination to a rich brat abroad who faced the heat for some reason which is not even clear.
When it comes to actually racism India is no better. So i would like to say this there is no point in talking against something which India has been practicing for centuries. If the caste-ism is not racism then why people are denied houses for rent just because they are of different caste. When ever there is a communal problem these dalits are made scapegoats by training them to attack others and if you see the death tool of dalits and other castes in these kind of violences, the no of deaths in the   so called upper classes are almost nil when compared to Dalits. They are even offered water in the coconut shells. That is the extent so discrimination we have. Isn't this racism?
Not only the casteism but also the discriminating and contempt towards the people of different region is very distressing to see. When the tourist come from the west and other countries people wont think of anything other than robing them.
So we have to acknowledge that racism is present even in India also and there is no point in complaining about the discrimination we face outside as we will be getting the same treatment what we have netted out to our own people. .....
