"I think it's at a different level - perhaps I'm wrong, perhaps a large number of people in this country think that some people are intrinsically worthless and you can do anything you want to them, but it's not an attitude I've encountered myself."
It's there all right. It's very noticeable in the rhetoric thrown at the poor (scroungers, shirkers etc), the working classes (who have only themselves to blame for not being accountants, lawyers and middle class rich - ha!) and in the realm of benefit sanctions, where many of the major sufferers are disabled. Also think of the anti-immigrant prejudice.
I'd argue that it is at the root of all male sexual entitlement towards women too - think of that thread about "what is the motive for this behaviour". Or any of the other threads about harassment. And the fact that they crop up regularly.
What you may be noticing is that the phenomena in India is a) more entrenched, whereas it has been questioned here for a century or more; b) more widely accepted; and c) (cricially) acted upon with greater impunity. What is really sad and depressing is that over a century of so many people questioning it here has not got rid of it entirely within our own geographic borders, let alone without. We seem to need to justify our own actions in this way as a social group, or social groups. It's an excuse.
