I think you're being defensive just for the sake of it. A lot of censored words were part of an imported default censorship list, these lists tend to be English language centric. We did add more words if and when they became an issue. I don't think we've had any issue with the word kaala or kaalu here. Sammy is West Indian and Perera is Sri Lankan. When you refer to them both together as black it's not because of them being a couple of West Indian or African guys. It's purely and solely based on their skin being darker. It's a racial slur in that specific context. A joke at both their expense. Forget all the periphery stuff and concentrate on the facts. Do you ever call anyone a kaala or a kaalu in a positive way? And if you do then is part of the positive mentioning of the word accompanied with laughter?
