Jokes aside, what matters is what you mean by words and how do you feel when you realize that what you're saying genuinely offends somebody. Imagine you don't really think about slavery when you say "sell down the river". Somebody points it out to you what it actually means. You can say "oh, shit" and try to avoid the phrase. Or you can say "it's my inalienable right to keep using this sentence". Or you can say "well, yes in this case it makes sense, this sentence is racist, but if we start to police words, where does it stop?"
Let's see; let's replace that sentence with any of the above. Is "whitespace" really a space for white people or is it because space between words is ink-free?
Is a "race condition" a condition of a race of people or a competition of speed? The words are spelled and pronounced the same but they are not the same word. One comes from romance languages and the other from Norse.
But it's not only etymology. Contrast "master" in "master-slave" where it clearly means the owner/controller of the slave and it stems from shameful practices actually happened in our past by and to our ancestors. Contrast this with "master copy", "to master an art", etc. where the word retains its original meaning of "teacher" (magister).
Be smart, be curious, don't stop at the surface.
