Imagine you have two cats - one is black and one is white. Both cats are equally cute and cuddly, but some people might prefer the white cat over the black cat for some reason. That's like how some people might judge other people based on their skin color, even if they are equally good and kind. It's not fair to judge someone based on something they were born with and cannot change, just like it's not fair to treat the black cat differently than the white cat because of its color. We should treat everyone the same, no matter what they look like.
