As previously stated, I find your opinion, as it was stated, to be worded in a way that may insult the other person. Given, the response did contain wording of similar effect, however, you stated that you can see how it might be offensive (which is a word I have not used, in contrary to your implication), meaning that you either noticed that in retrospect or typed it with the intention of insult. That is the thing that is undesirable about your comment.
And to answer your question, yes, I do care because a person with whom I am acquainted with in a rather positive manner is afflicted by this argument. I will not try to deny that their responses were not ideal, though I do feel the need to state that your opinion is not, in fact, respectfully worded.
