I think this probably wasn't the intention but I think most people will read nihilism into that. ("My parents have no self... so, why should I be angry if they were insulted? I've freed myself from that nonsense already!!") It's inappropriate.hermitwin wrote:non-self. anatta.

of self.
if there is no-self, how can you get angry
about your parents getting insulted???
I think the better question is probably to ask whether an arahant would think that having anger is conducive to nibbana.
Also, if the person knew that it was the arahant's parents, I think it's unlikely that he's going to insult them. If he didn't know, then I think he's probably going to apologize profusely when he found out. Why would anyone be angry at that?
Even if the person had no idea what an arahant was, I think he will still feel guilty once he met the person. Can you imagine this happening with anyone who gets angry?
