I see it as being more about demographics.
I agree with you about demographics which is why I suggest that snobbish comments should be avoided, with chicken korma and chicken tikka masala being promoted far more.
How can you say that nobody should want to discuss the music of two leading artists? It's like you probably think that nobody who is 'seriously' interested in BIR food, would want to discuss/make either of the two most popular dishes, by far.
Next, you introduce the other commonly used slur - that kormas are only for women. What nonsense. I used to like BIR kormas, presumably because I have a sweet tooth. I avoid them now, because BIR food quality has gone way down hill since the 1980s.
The comment about women is also irrational because the demographics are that men and women are both about 50% of the population. So, if you comments were correct we'd presumably see containers of chicken vindaloo or similar, piled as high as chicken korma. But we don't, so you must be wrong.
