Even if that's true, there are still many other HN readers watching the conversation who may be more open to logical arguments from either side.
So I think it's still "worth it" to respond in a meaningful way, even though you may not convince the original poster.
And considering it's possible that debating someone's strongly held points with logical counter points will only irrationally strengthen the person's original beliefs anyway, I think humor was appropriate:
