Yea but you can always tell it’s an Indian because they write differently from actual English speakers.
Sure, but a lot of times it's not really Indian English, it's English vocab mixed and matched with grammar rules from other Indian languages like Hindi or Urdu or Bengali. I've been on conference calls where Indians from different regions were speaking mutually unintelligible versions of English and had to act as a translator from english to english.
You may personally like one or another better, you may find some particular varieties easier or harder to understand, but that doesn’t make those people any more or less ‘actual’ English speakers than you are. They are ‘actually’ speaking English, just like you.
If you wanted to phrase this in a less fraught way, you might say “Yea but you can almost always tell it’s an Indian because they tend to write characteristically distinct from <your nationality> English speakers” -
and I would agree with you, sentence structure and idioms do usually make it pretty easy to recognize.
to what end do you employ this analysis?
