I for one call blacks blacks, as that's what they are, no changing that (unless your name is Jackson)! There's nothing wrong with it, there's no resentment or hate when I call them that, it's just a word, people need to learn that words don't really mean that much, attitude matters a lot more. It's like saying that it's a bad thing to call a bulldog a bulldog, like seriously, it's just a race and a simple word that is somewhat linked to it, no need to go out of your way to not offend people. Just like how I don't feel a thing when called a white, black is fine to refer to people of that race, as long as it's not said in a mean, vindictive, resentful or hateful manner, it's the least people need to worry about
