science

There's no real scientific basis of there being such a thing as a "race". There's many more sub-phenotypes of homo sapien than there are "races". Hell, in Africa alone there are something like ~~14~~ edit: 13 (sorry, had to fact check myself there) major, distinct genetic groups [1]. Many of the major pacific islands also have distinct genetic lineage; so much so that they can be reliably grouped into which island they originated from. "Race" is far too broad of a term and wholly unscientific; it should be broken down in a far more granular fashion. (in my opinion the benefit of this being that it's unlikely to be worth it to racists to remember all the groups they're trying to hate)

The comment was a poke at the people (like yourself) who always jump to the conclusion you've jumped to; as well as the scientists who constantly walk on egg shells to avoid any topic like intelligence, because they will be roasted alive by hypersensitive people who are just looking for someone to attack. So their findings, and their reports are chastised in order to fit that particular nuance of our society.

Additionally, the reason I think we should stop shying away from distinctly organizing these genetic groups, is because in lots of cases of medical research, these genetic lineages aren't being taken into account. Many drugs work differently on West-European patients than they do on East-Asian patients; or have different efficacy. These things need to be taken into account if we're ever going to create the right medicine for the right people.
