I agree with Gene that this is not a cause for concern.
I also do not find his very direct response to be offensive. Everyone has a different style and manner. As long as a response is not nasty or distasteful, I think visitors will be able to understand that we all have different ways of communicating and presenting ourselves. I am sure that there are folks out there who do not like my style of presentation. And that's okay. Let's not censor style.
