It's not in response to that, but in response to the question about caste and the internal struggles of these two groups.
This is an extremely important issue that very few people outside Sri Lanka know anything about. I'm not going to enter into it now in any detail, except to say that caste is a phenomenon of the Indian subcontinent that spread over into Sri Lanka. It is a topic, like your sex life, that you do not discuss in public; it's a very private thing. But in the context both of the Sinhalese population and of the LTTE, there have been internal caste wars, and they are definitely part of the complex background of this, which we often ignore. That just shows you how culturally entrenched this is, that even economic issues become exposed to a cultural interpretation, which makes them all the more volatile. It's almost as if nothing can escape the black hole of bringing any apparatus or part of what it is to be a Sri Lankan today into this ethnic maw. But certainly the caste thing is a complicated part of it, and I wanted to mention that it's something we don't know much about.
