That makes sense, but then what is the purpose of the 'foe' label? I can see the logic behind using it as a time-saver (as described by conesus) or a reminder that engagement will probably be unproductive. But if you intend to learn from and engage with the foe, it seems like the 'foe' label is just going to prejudice you against their comments before you read them, without much benefit.
