The statement was obviously about personality traits, that much was clear based on the context in which the statement was made (this HN thread). You are now ignoring the context in which the statement was made and instead focusing on the use of the word 'context' within the statement itself. To make it easier for you to understand, here is what was implied by the statement given the context in which it was made "There's literally no context where attributing PERSONALITY qualities to people based on their skin color is OK."
Your argument about medical conditions is not only wrong (as pointed out by another commenter), it's completely irrelevant and off-topic. The discussion was only about personality traits until you tried to derail it.
