TTG has a scathing attack on why the term South-Asian is a wrong nomenclature. I completely agree with him.
So pardon me, if I take offense at being associated with a bunch of suicide bombers, and fundamentalist pricks. Of course, one argues that the “average” Pakistani and Bangladeshi is not responsible for these characters either. Which may or or may not be true, but the fact is, that we Indians have worked hard to carve out a name for our country – it stands for something. The Idea of India is not a new concept. It’s been around for a good 2000 years or so. Replacing the Idea of India with one of South Asia devalues everything that India has achieved to group it right back with a surrounding basket cases.
