So, before asking such kind of answer; how could we understand which terminologies may be considered as attacking/ racist/ hurting etc; and which are safe; and how could we make our sentences 'moderate', so that no-one feels inferior or superior.
So we should have some sort of guideline. Isn't?
Since by-definition science deals with truth; in subjects like anthropology, human-biology, genetics, genetic disease and their control, etc; inevitably every times there will come discussion about genetic variation in human races or populations. May it be about lactose-intolerance or sickle-cell-anaemia. If we censor them out; world's knowledge would be tampered.
So we should have certain guidelines as well as certain amount of permissions too.
