I'm afraid you will have to include the quote that you would like us to analyze if you would like one of us to intelligently answer this question.
I am guessing it is the following (arguably) most famous quote that Huck spoke in chapter 15:
Huck’s racism prevents him from seeing that Jim argues well.
It was fifteen minutes before I could work myself up to go and humble myself to a nigger; but I done it, and I warn't ever sorry for it afterwards, neither. I didn't do him no more mean tricks, and I wouldn't done that one if I'd a knowed it would make him feel that way. (15.49)
What this quote says to me is that although Huck was raised to be racist (note the use of the N word), that he has the character to break out of his upbringing and see people for who they are. He still sees Jim as lower than himself as evidenced by the fact that it took him so long to get up the courage to "lower" himself to a black man in an apology.
However, the fact that he felt good about the apology afterward...and that he vowed never to make even a black man feel badly because of him in the future...shows that Huck is a thoughtful, independent, moral young man who isn't afraid to buck society if he thinks it is wrong.
