Eh, I would say everyone has the right to feel however they wish; be it happy, sad, angry, or even offended.

Now, you are not entitled to have other people care about your emotions, but that is rather a separate issue. If you feel they haven't adequately defended their reaction you are of course free to disagree, but your right to disagree should not be misconstrued as a lack of a right to be offended on their part.
