":::Mudblood is meant to be AS offensive as the n-word without actually being the n-word; so in a sense, you're correct.  In the series, it's used the same way: as an inflamatory insult brought out by the hatred of someone's liniage.  But simply beacause you see mudblood and think ""n-word"" says more about your personal perceptions than it does the intended use of the word.
