True, but a premillennialist is not committed to believing in a "literal" chain etc. A premillennialist would only claim that the Dragon is rendered powerless (at least so he cannot deceive the nations) for a thousand years (however long that is) however that is done. Now, reading the thousand years as a symbol for the interadvent period would be odd given that there is evidence that Satan is in power thoughout the New Testament written after Jesus' death (and in modern times if the Holocaust and the like is any evidence). In fact, in Chapter 12, Satan is thrown to earth after the death and ascension of Jesus. True, Revelation is hard to interpret and symbols are used, but that doesn't mean that "everything goes".
I wrote my post in response to many of the points made in those articles you mention. Let me address further the point that 19:11-21 conflicts with 20:1-10. First, those who claim this do not even address the fact that it is only Satan (of the evil trinity) that appears in 20:1-3 and it is only Satan (of the evil trinity) that does not appear in 19:19-21. This fact is evidence of a chronological tie between those sections. Second, does 19:17-21 really claim that everyone on earth is destroyed by Jesus? First, this would be odd just on a common sense level. This scene is a battle and elsewhere we are told of a location for the assembly of the combatants (16:16). It would be odd for everyone in the world to be part of this battle. Proof of this is that those mentioned in 19:19 are military persons and it is to these that "the rest" in 19:21 most likely refer. That leaves 19:18. Notice that the roster begins by noting military descriptions (kings, captains/military leaders, strong men, horses and their riders). The addition of "the flesh of all" need not mean anymore than "the flesh of all involved in this battle" be they free or slave, small or great (I'm not sure a lot of weight can be made of these last descriptions since they seem stock and trade--13:16, 6:15, 11:18). Second, the other descriptions of the battle also mention military persons (6:15, 16:14).
Another factor is that Ezekiel 38-39 is drawn from in both 19:17-21 and 20:7-10. However, this doesn't prove the same event is being describes. First, there are differences between the descritions (see my post). Second, Ezekiel 38 and 39 could be read to refer to two different battles, one in which fire is used to destroy (38, cf. Rev. 20:7-10) and one in which flesh is eaten (39, cf. Rev. 19:17-21).
