I don’t agree with the assessment that white people laugh at Indian-accented English because they are uncomfortable. Indian-accented English is clipped, and if the accent is thick, hard for people unfamiliar with it to understand, true. But also, apart from the actual pronunciation of words, Indians tend to use voice inflections and emphases in their speech that native speakers of English use as humor cues in their day-to-day speech. While I think most native English speakers understand that this isn’t intentionally done, it still is humorous. Personally, I would think it very tiresome to have people constantly finding humor in serious (or even just mundane) things I was trying to say, and it’s rude to laugh at anyone’s accent, period, but there is a cause for this phenomenon other than cruelty or discomfort.
