> India is not what even the most casual racist would consider "third world".

I don't follow. India was Third World in the original Cold War sense as a founder and leader of the Non-Aligned Movement, and it still fits the term's colloquial sense through low GDP per-capita, poor HDI figures, weak state capacity, corruption and uneven infrastructure.

The label might be offensive, the comment you responded to most certainly is. But excluding India from the Third World is hard to justify.
