I actually do believe that Revelation is largely written in parallel structure, but not this individual chapter. You've just read a lot of stuffs that's not in there.
Really??? What of the following is inaccurate?
Notice the chiastic structure.
[A1] Revelation 12:1-5 KJB = Woman, Child and Dragon
[B1] Revelation 12:6 KJB = Woman in Wilderness for 1,260 days [years]
[C1] Revelation 12:7-9 KJB = War between Michael and Satan in Heaven
[D1] Revelation 12:10 KJB = Cross, Power of Christ, His Victory
[D2] Revelation 12:11 KJB = Lamb, Blood of Christ, Their [overcoming saints] Victory in Him
[C2] Revelation 12:12 KJB = Dragon permanently cast down to Earth fights against Jesus' body
[B2] Revelation 12:13-16 KJB = Woman in Wilderness, for a time, and times, and half a time [aka, 3 1/2 times or 1,260 days [years]]
[A2] Revelation 12:17 KJB = Woman, her Seed and Dragon
An example of another parallelism within the greater:
Revelation 12:7 KJB - And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,
[A1] Michael – Leader
[B1] his angels – Followers
[A2] Dragon – Leader
[B2] his angels - Followers
