Obviously this isn't the other wiki. I saw that a user here made a Q & A thing and said they were talking to a writer, but then two users just started adding in their own ideas as answers. Such unconfirmed information like that should never be added to articles, just stick to what we see in Supernatural itself.

It isn't as simple as you say. When Death said Leviathans can kill angels, he was talking about the thousands or millions of lower level angels, and didn't think it would be necessary to distinguish the 4 archangels out of 1,000 or 1,000,000 angels. Besides that, he would have no point to, as two of the archangels were dead, and the other two are locked away in Lucifer's Cage.

Why are you so adamant to put this asumption into pages? And yes, it is an assumption, because it wasn't explicitly stated in the show, and you are assuming this to be the case. And before you say again that they did say it in the show, they did not mention archangels specifically. Archangels are angels, but all angels aren't archangels, at least in the show, and all other official Supernatural content.
