We're telling you how this particular set of people are likely to react. It's fair if you did not know, and referred to the best source you could find (the dictionary). But now you have more data, and can adapt now. A natural response is that you can't do this for all words with all people. But you don't need to do that. Once you learn how people respond to a word, you can change. It's how we learned what to say and what not to say in different contexts - surely you didn't check the dictionary every time someone told you "That's not appropriate here."
