Just sounds like pedantry to me.Went to Abergavenny Food Festival and saw a demonstration by Cyrus Todiwalla. He had a good rant about people always saying they are going for a curry when they are going for an Indian. He, quite rightly, said that there is not a dish called curry on an Indian menu. When people go for a Thai, when there is red and green curry on the menu they never say they are having a curry, they say Thai.
curry1
/ˈkʌri/
noun
a dish of meat, vegetables, etc., cooked in an Indian-style sauce of hot-tasting spices and typically served with rice.
"we went out for a curry"
It's a pretty broad definition which includes all of the above I'd say. It may not be what a 'curry' was originally, but this is how it's understood by most people I think.
