On my answer to the question When referring to races, should 'black' and 'white' be capitalized? (MLA), another user has posted an up-voted (5 at present) comment that contains new information. Another user has suggested that they should write it up as a separate answer but they have not done so to date (9 days later).
Should I incorporate the information from the comment into my answer, giving proper credit to it, or just leave it as it is?
