I reminded you that you shouldn't be rude. You don't need to be rude to get your point across. I was arguing in favor of the same perspective, I was insulted by the same person, but I managed it. Frankly I find it absurd for you to say this person is "behaving like a child" and then, when challenged on your behavior, to turn around and say "they started it." I don't think there's more to say; have a good day.
