With all due respects, I don't agree with this at all.
I'm not sure what is so distasteful about speaking with the accent of the country your born in? I would love to have an Irish accent, lol, but as I am born in the West Midlands I talk in that way instead, it's not something one has a choice in, and it's definitely not being sycophantic.
btw, it irritates me as much as anyone else if I see someone rejecting their own culture for another out of shame or embarrassment. We should all be proud of our roots and cultures but not in a way which gives us the impression we are superior to others. I wear the jilbaab on, because it is just so practical and comfortable for me, and so many people accused me of adopting Arab culture as I have some complex about my own...and funnily enough it is those people who'll complain if you do something too 'Kashmiri' or 'Pakistani'. Neither should we have an inferiority complex about ourselves, and nor a superiority complex.
Ok, fair enough comments. I suppose one really can't completely avoid the accent of the country they are born in. Still, this doesn't change the fact that many Asian immigrants (as you also agree) become sycophantic and ape the mannerisms and ways of the kuffar in order to attempt to try to not "look out of place" in front of them, even though this is actually futile anyway given their racial characteristics automatically render this impossible. I fully agree that one should take pride and never become ashamed of their race and religion and culture and roots of their country of origin. When Asian sycophancy and aping of the Western kuffar takes over, the Western kuffar can SEE this grovelling and sycophancy and they either openly or secretly laugh at the weakness.
