There's no pleasing everyone. In fact, people get upset over the dumbest things. Sure, it's a good idea to be polite and not go out of your way to make people feel bad. However, sometimes someone is going to misinterpret something or take something extremely personally, and that's just a part of life. You can be minding your own business eating a slice of pizza and get a stern talking to. There's just a lot of absurd things people get offended by.
