I've had the pleasure of meeting enough sub-Saharan Africans that I can not only personally call bullshit on this, the statement is so nonsensical it reads to me like a claim that the moon is made of Swiss cheese.

Of course it has negative connotations. Most people don't like racists. You can't seem to deal with that, and your weasel words make you a coward. Whose respect are you trying to earn (or keep) anyway? I'll tell you something, owning up to it won't lose you any more respect. But at least you'd be less insufferable.
"Racism is generally defined as actions, practices, or beliefs that reflect the racial worldview: the ideology that humans are divided into separate and exclusive biological entities called "races". This ideology entails the belief that members of a race share a set of characteristic traits, abilities, or qualities, that traits of personality, intellect, morality, and other cultural behavioral characteristics are inherited, and that this inheritance means that races can be ranked as innately superior or inferior to others."
Why are you arguing about this? Your homework is to go out and tell everyone you know that you're an unrepentant racist.
