Some of us are farther along on our journey than others. It could be this person is at the beginning of theirs and hasn't learned to not react to some things.

If it wasn't directed at you, then perhaps the thing to do is make a mod or admin aware of it. That way you have done your good deed and not involved yourself to the point of pain.

BTW, I'm well aware that this happens at times and I so do understand where you are coming from.

Take care of YOU.
