I think you should also take notice those people who uses word Bharti instead of Bharati
As explained many times, Bharti is in the official Urdu dictionary. It is nothing offensive.
We have a slightly different way of saying many words.
Egyptians call themselve Masri, we call them Misry
Arabs call themselves Arrub or Arrubi. We say Arby.
Indians add an "a" to many words which, when used in Urdu don't use the ending "a" sound.
Bhartiya becomes bharti, all news channels, Geo, Aaj, Dawn would use Bharti, who all will we change?
Indians too can't really say Pakistani the way we say it, its okay thats a lingual issue. Racial slurs are a racism issue.
Then set an example and apply the "danda" equally. I am not questioning your moderation, just pointing out what indians find offensive.
We have banned many other racial slurs often used for Indians. Rat references, lady-finger references. Heck I wouldn't use the word Mallu but Keralites here have said they find it cool, so now Mallu is okay (I always found it to be a racial slur, though as I know people who used it as such only).
