Perhaps the real question should be, "Why do some Christians feel the need to assign
derogatory and inapplicable labels to people they don't agree with?" It isn't just the "atheist" label, there's plenty of others, like the ever-popular, "He's not a true Christian."
Emphasis mine.
Strangely, when considering that being a "True Christian" is being a close minded individual (since the ones calling you "not a True Christian" overy often are), I don't see how being called "not a True Christian" can be seen as a bad thing. Now, being called "not a Christian" when you are one, I can see that being painful for someone, but since no one can agree on what a "True Christian" is anyway, I don't think that term could be seen as very derogative.
I hunt for the truth
