How are they different? It appears you agree that if one does not like the rule they should not go. At the same time my impression is that you still want to go but dislike the rule.
I think its that the rules they agree with are okay, and everyone should agree with that. The one rule they disagree with isn't okay. We're left to guess which rule isn't like the others. I personally would find it very strange to be asked to show up in my birthday suit.
