I agree with your "labelled racist by who, how do you count, etc" questions. But that just throws the meaninglessness of the original statement into starker relief: it's simply an empty expression of unsupported complaint. Your finishing formulation, is unfortunately simply more prolix.

I do not see those sorts of comments as up to the usual standards of HackerNews. Perhaps to be expected on an article like this, but still they should be discouraged.
